Red_Tourer

I assume by now you've solved this one but in case you haven't, I've never had a CD2/POI disc and I've done several updates. I've only ever had 3 discs. For what it's worth, using DVDs is very slow. I usually transfer the contents to USB sticks and use those. Also, if you have a later version of the firmware, it's possible to perform the updates while driving. With the early versions that would cause a problem due, or so I was told, to the tyre pressure sensors. I've also done several firmware updates and it's not worth transferring those to USB as they're quite small. The latest version I have of the firmware is NG4_42.03_N42c (taken from the test describing the software on the disc) and the latest maps I have are 2016-2 which is the latest from citroen.navigation.com
