I have retrofited amundens in my skoda rapid. I have also installed new antena with gps. Nav system worked at first but not always, I couldn't set navigation and just not positioning where I really was. Then it stopped picking signal compleatly. I bought on aliexpress gps antena which should work as I saw a lot of people buy those antena for nav retrofits but still nothing, now even nav menu won't start and displays that it doesnt have media with maps.
Annyone have similar experiences or know how to fix?

I was also thinking to retrofit revers camera but i want to fit higline instead of lowline, as far as my reaserch goes it shuld work but i was thinking if anyone have octavia/super/kodiaq etc. with this camera if handle is same size as on rapid or other cars. This would made retrofit easyer and cheaper.
Also didn't find no info on if you could opt revers camera with only rear sensors or you need to have front too.

If I need to retrofit front sensors for camera do I also need parking sensor button that comes under climatronic or not. I know that I need this button for higline camera to power it on comand without putting it in reverse but don't know if I need it to put that for camera to work normaly or can I fit that later.
I was thinking to go step further and install parking aid from octavia/superb so I could have 4 rear sensor insted of 3 and 4 in front with 4 side sensors. This should work as I have amundens unit 5q0 035 874 b wich could also be in those cars with that system and its able to display informations. I would be happy to see if any one have some more informations about those systems if it would work what do I need to be prepered for or if anyone have already done it.
I was thinking to put this question on octavia/superb forum since they have this systems but I would start searching for answers hear : )

Thansk for any informations or help

@Zan I don't know if this stuff will need coding in with VCDS or something.
