I have a Connect Nav+ unit (magneti marelli) in my doblo (not the stilo version). After I build in a Parrot carkit, it does not have a GPS fix anymore. I already tried a new antenna, but also without any luck.

Are there any hidden menu's in the navigation system such as in the Stilo system? I'd like to reset the units' software and see if that has any effect. Another option would be to update the units' software, does anyone know if the software is available to download (not the maps, but the firmware)? Or are there other solutions to fix the problem?

I would check for any software updates they did something to the satellites about 3 months ago and my tomtom needed a fix to receive again.
