Hello,
did you ever resolve this issue successfully? My Opel Grandland X, which is based on a 3008, has the exact same issue. I already installed the latest firmware and maps. The error still exists.

I resolved the problem after few weeks of reading and studying. You have to replace the NAC ("the multimedia computer"). You can do it yourself or you will find someone who has some knowledge with computer programming / Arduino and time to read. I replaced my radio NAC Wave 2 with a used NAC Wave 4. Pay attention whether you have a DAB+ and whether you have a HD or non-HD version. If you have a non-HD version you have also to take a non-HD version. Otherwise the graphics will not look good.

Or you will drive to Peugeot / Opel and they will do it for huge money for you.

Here is a link to the French forum (copy it) with the Arduino tutorial:
