Citroen C5 2009 resetting/Bluetooth?

Post by IAH343 »


My Citroen C5 2009 has been resetting at random times and I've no idea why. Everything stays the same, but just annoying really.

Software version: rneg_D_r20ter_r20.07

There's an SD card in the front of the panel, which is the navigation system, is that where the firmware is installed? Does it need an update?

Also would a firmware update get Bluetooth music connectivity? Just wondering. Could someone walk me thoroughly though how to update firmware, and fix this issue?

The MyWay system you have does not support Bluetooth Streaming - only the telephone and address book synchronising.

The CD does support playing MP3 CDs - so you can cram quite a few MP3 tracks onto a single CD - just make sure you format it as an MP3 CD when creating it. You can get a hundred plus tracks on depending on size and bit rate.

As for the firmware, yes there has been a few updates since the version you are on. The latest version R50b does fix the random restarts. I created a post on SD card upgrades here:
MyWay / RNEG Upgrades , but to be completely honest, I personally would go to the dealer and order the upgrade CD direct. It should only cost a couple of £s and will circumnavigate all the SD card compatibility issues that some people have had. The CD is part number: 9679240380. Citroen will be able to order this for you, then you can do the upgrade straight off the CD.
