NG4 oh no it's not well.

[ChrisRobin]

Well still not working. Took unit out, removed hard drive and plugged it into my pc and all partitions read ok file system ONX if I remember rightly last one is something like system managed so I guess that is the juke box, so to me hd is ok, did more googling and found a French chap from 2015 who says the cd player can cause issues and stop the unit booting the KLM loops (what ever that is) Google translate wasn't too bad but his link is no longer available so I don't know how to disable the DVD, I tried removing the ribbon cable completely, along unit back in car what an awkward git to get back, this time still no boot but no buzz either, so out it came again, double check on fuses including one on back of unit, all ok, inserted new HDD and retfitted ribbon cable so cd is live again and slung unit back in again, still no start up but buzz is back does not boot usb for firmware. So not sure if cable removal was right or not as cd is master I don't know if OS would refuse to boot as no master is detected, is that intelligent? So we are back to square one but with a little more info and a unit part number.
The ribbon cable was very tightly folded so I wonder if it is damaged, so trying to source another also have the part number of the DVD player, but think I stand a better chance of finding a real unicorn to be honest. Find it amazing that you can get Bentley nav systems repaired and the new round mini ones but not this one unless you send it to Poland (rather expensive)
If I can get a ribbon cable for it or find out to disable it will go for round two.
Annoying if it is the DVD as we have never used it always played from sd, no need for it. Our 307 was plagued with cd issues both radio and multi changer.
Update: found a new DVD drive from Germany £179 brand new just need to prove somehow it is that, was hoping for cheaper to test but it an option at least.

[GiveMeABreak]

Yes that's correct there is a master / slave configuration with the master being the DVD and the HDD Slave.

[ChrisRobin]

Right, so if it works the same way as a PC if I disconnect the master boot device OS can't do the "handshake" with it so wont boot anyway providing it works the same way which I would imagine it does in a fashion, interesting! so in theory then I would need to find some one who can change the master boot device in its bios (if it has one) to possible USB/SD, or prove to myself if it is actually DVD playing up, shame someone on here does not have an old unit chucked in a shed, the OS must know which is master and slave as the HDD is not jumped for salve it is bear so usually that mean cable select. Starting to wonder considering you can not get any parts for these units why they are new DVD drives still on the market for them, makes you wonder if the DVD drive is the root of most problems on these units does it not, which is why you can still get refurbished NG4's because all they have done to get it working is change the DVD drive and reinstall firmware and maps on HDD and Boom 800 Euros thank you very much, so is that why are they still available on mass, yet you can not get a Toshiba hard drive.

[GiveMeABreak]

You can't do that I'm afraid it's not like a PC. That's why in my upgrade guide you have to ensure the jumper settings are correct on the IDE Card Adapter (where they have them).

The other issues are not really anything to do with the DVD Drive that I can see. Most people I know never used the DVD, opting for Jukebox or SD card for music and I've never known the DVD hardware to cause these issues. It is entirely almost the HDD itself that is failing or a fault in the code on one of the chips on the motherboard.

[ChrisRobin]

Ah right, just found it odd no jumper on the old drive, do you know of a member close to north wales that can "read" these units most people I know have the VAG software or generic diag testers which do not look deep enough, I did find a list with a map with pins on it but I can not locate it now at all, because I am looking for it I suspect, I have tried loads of audio repair specialists and all come back as, no we don't repair them, one chap did say that he thought it sounds like DVD by the description of fault and he has done a couple of them but they are not his field, he said he disables the DVD so you can not use it, or he can get a cable @ £80 for it if it needs one will cost me £200 plus post both ways and cable price if it is that which I thought was a bit expensive, hence the research into DVD problems and the French chap, so it is looking like into the skip with it then and a real feeling of wish we hadn't gone Peugeot again, this will be last one we own the wife does not want another not with the dial lights and now this media unit has just about finished her off, Everything is just hassle with them, can't find anyone with a Pug tester, to diag it yet with Renault I can, can not find anyone to repair its nav unit yet Renault I can, can even find a Bentley repair specialist but no Peugeot... incredible disheartening indeed and I really want to say "I told you so" to her but that will not help, So I will try and talk her into a cheap Chinese android unit for it and get rid quick sharp before it plays up again with another unrepairable problem.

This is unfortunately going to be an ongoing issue - the NG4, although a premium system is old now, having been developed back in the mid 2000s and coming to market with PSA in 2009, so with development is about 18+ years old.

The later touchscreen systems are now integrated into the vehicles in common with many other manufacturers, so repairs will not be for the DIYer as there's no parts that can be replaced realistically. Nothing unique here to PSA vehicles though - you'll find this in most manufacturers.

Be aware that you may likely lose some functionality with aftermarket units though. I know the NG4s are expensive as even on the second hand market they are about £800 and upwards!

As for members with Lexia / Diagbox, not that you'll get much apart from a fault code - but often these will not provide anything meaningful unless there's a comms fault. You can test button presses though and a few other things.

[ChrisRobin]

That's the list, could not find it, saw it last week but blind to it now, thank you, loss of functionality is no problem got none now at all, not even parking sensors, I just find it infuriating that there is no help on these, yet even for the new VAG in dash units you can get them repaired by "people" obviously not us but there are people who repair them even the 5F glovebox units that integrate with the whole car cost you a start price of 2K dependant on vehicle, yet they repair them and keep it coding for you , so it is straight out and straight back in no need to bring it to us for coding back in, incredible, yet NG4 Nope don't do that. This why I thought I had talked her out of Peugeot considering the last 2 years of the 307cc with constant EML lights on and sensor chasing I was really surprised she had set her heart on this 308cc, yep it looks nice but you get no help with it, My Renault Tech works on it best he can, did have a pug tech well 2 over 7 years, but they don't like it around here when they find out you are also in "the trade" and that avenue dries up quickly, so all our spare money which she wanted wheels for the 308 (that in itself is a joke, talk about expense as it is 4 bolt not 5) has gone on repair of dials so they light up again and now the rest on the media unit apart from we haven't actually got £800 to spend on a old refurbed unit, so I am hoping that after this major expense she will be so fed up with this car it will go, after 12 months of ownership I can only hope, everything I try just fails, I can not help her with it, you may as well just say it's a Koenigsegg as you get the same amount of help around here for that as you do Peugeot, NEVER again! and if she tries I will remind her of the cost in time and money this 308 has taken from us in 12 month of ownership, I feel so sorry for her, she was almost in tears last night because of the expense of this car and like I said "told you so" is what i want to say but that really will not help just make her even more upset, every ally you go done ends in no sorry, no sorry or give me £200 and I will see if I can repair it. Can't even sell it as it is, who would buy it with no media system working in it they would offer peanuts. Great!

[GiveMeABreak]

Ok, I understand your frustration, best of luck with whatever you decide on doing.

[ChrisRobin]

Tell me, you seem to know an awful lot about this QNX OS by what I have been reading on here over the past week, can you tell me how it would look at a DVD drive, would it see an just an optical device or does QNX look at specific drives in other words would it need a reference number like a serial number to tie this drive to it.
Reason: found a BMW dvd drive identical to NG4's apart from NG4's is DV-04-080c and the beamer is DV-04-080A but identical to look at @ £25 or offers, now if NG4 sees just an optical drive only at the end of that cable then there should be nothing in theory stopping me attaching this BMW drive to it and NG4 knowing no difference.

[GiveMeABreak]

I can't tell you is the simple answer, QNX is just the automotive operating system and needs drivers like other OSs - but I suspect it is a generic Unix driver. These units (or a variant of them) are supplied to BMW and some other manufacturers including Mercedes IIRC in the past, as the mapping software is similar too. This is why we can get a 'make do' update to the maps for the NG4 which is a version of the BMW version, seeing as PSA stopped commissioning map updates from 'Here' maps after the 2016-2 version, much to the annoyance of owners.

[ChrisRobin]

MMmmm in that case swapping the unit with another of the same model could well prove my point to myself, I think it is just an optical device, I have fitted many to PC's over the years and very rare put a driver in unless you go from read to read/write, and many different makes it all depended what I could scavenge from a broken PC's you know what the motor trade is like.
I suppose what I just can not get out of my head is why the buzz from the DVD drive, what are you looking for and more to the point WHY can I hear you buzzing you have never buzzed before you have pinged that drive in silence for 12 months, Drive will not even take a CD at present you can push it in but it does not "grab" it and take it in so something is a foot with the player maybe something has dried up as it hasn't been used or just plain given up, will find out when it arrives and I chick it in, no mean feet a 6 foot tall I tell you, gettin me shovel hands into the back of the unit, neighbours be exposed to more expletives next weekend as I force me hands in again, or it could end up on garage roof, tell er in doors wind blew out my hands, sorry!
I shall let you know.

Noticed same guy was selling a Toshiba drive as well (Same as the Pug) but it a SATA one, not that I need one, strange how close yet so far apart they are.

[ChrisRobin]

NG4 FIXED...... Well done BMW for donating parts.
Just got the some what harder job of convincing the wife to get rid. And never let another PSA darken our drive, I think fixing the NG4 will have been easier.

[Hristo Ivanov]

Hello everybody! I'd like to ask for help. My NaviDrive NG4 died couple of months ago. The only repairman that agreed to try and fix it, gave up after awhile. Said it was a DSP chip that is faulty. Also said it is better to look for another unit which I cannot find nearby.
I managed to open the headunit myself but cannot find this DSP. Probably out of desperation but I hope that this chip could be replaced. In order to do so I need to find it and see the exact symbols on it. If anyone has any idea how to help I would be very grateful.
Thanks.

[GiveMeABreak]

I don't think you'll get any help regarding this issue here. If it's hardware related then you are on your own as to getting it replaced, as PSA don't provide internal schematics of their units as they do not repair them. They are sent of to approved audio repairers like Clarion and charge the customer accordingly.

These units were made by Harman Becker.

[Hristo Ivanov]

Thank you for the quick response!
Too bad that the repair guy was actualy from a official Clarion/Becker ans so on service. So it is a dead end I guess.
Anyway, does anybody have any experience with an aftermarket multimedia. Any ideas that would provide the functiinality of the original unit, are welcome.
