I've tried to find the answer to this myself and it does not appear to be here... loads of threads but nothing that I can see that's clear; apologies in advance if I have simply not looked properly.
I have 3G HDD nav, DVD player, front / rear park plus.
So I'd like to install a reverse camera > the question is do I need an interface or as I have the spec above already is there an existing point somewhere that I can plug into already ?
Was looking at item Veyron VC-AUTT Reversing Rear-View Camera for Audi A5 | eBay
Anyone know ?
