I was leaning towards getting a Uconnect7 unit and fitting it, but I just called to a used parts lot and I laughed hard when the owner told me that he wanted 250€ + VAT (which means a 310€ total) for a USED unit!
I found on AliExpress
this one which seems identical to the Erisin that has been suggested on this thread. The 4GB RAM unit costs only 147€.
P.S. I found another Uconnect7 unit for 160€.
What do you think, lads? Is it worth it or should I get the aftermarket one with the same money?
P.S.2
I am also looking at
this one. Much larger screen and, judging by the reviews, it seems nice.
