Hello Mark,

Today i swapt my RT6 unit for another one.
Everything works perfectly fine, all buttons are doing what they suppost to do.
The only thing is that there is this Beep, and i believe it is there because of the different VIN numbers from the car and RT6 unit.

How do i get rid of that??

Greetings,

Michael

Yes, that's because the unit needs VIN-coding to your vehicle. You will need either a Citroen dealer or somebody with Diagbox or other professional level diagnostic kit to do this for you. Expect beeps and other annoyances until this has been coded.

Hello Mark,

After put in the other rt6 unit and a visit to the citroendealer, everything works like it should be!!!
So i am very happy with that.
The only thing is a want to upgrade the firmware, without getting any problems, can you tell me please what the best way is to do this??
It is now i believe 2.31

Greetings,
Michael

Ok so for version 2.31 going to the latest upgrade (2.86) will likely cause the unit to go into secure mode as it is a major update from what you have. This may involve a visit to the dealership afterwards if you lose your vehicle configuration.

However, if everything is working correctly now and all the options are correct, then I suggest if you first use the Mirascripts Part A to backup your user data and configuration, then complete the firmware update, you should be able to use Mirascripts Part B to restore your settings back to as they are now if there is a problem. I can't guarantee this of course as each model and unit can behave differently.

The guide for the Mirascripts parts A and B are in the guide here - just refer to the relevant sections (and ignore the rest of the guide) to backup and restore the user data files:

And again....all the buttons gone!!! but now worse then the first unit, no button work anymore.
couldn't even set the unit back with a back up i made

Ok, so it looks like you may have to go back to the dealer to check it again - these units are one of the worst to deal with issues like this as there's nothing much you can do when they lock down.

You do not believe it, but i fix it!!! Had a other sd card and format it, install the new firmware in the car and it is working like it should be!! It is a miracle hahahahha
