I have the old 4:3 satnav unit, but i assume it's the same set up in the trunk..?
I bought my X5 from a bankruptcy auction, and it looks like the former owner had removed a similar unit and just throwed in the old OEM system.
I think i was supposed to have a OEM cd changer, but it's not in the trunk.
The nav/cd unit in the trunk doesn't work at all anyway...

I'll settle for the Eonon then, easyer to find help if i need it ;-)
