Swapping radio module to get aux-in

[UCrewX5]

Yes, it's a plug-n-play swap of the radio module, and if you have nav then the radio module part is the same whether you have DSP or not.

For those with non-nav, I believe what you need to swap is the dash CD (or cassette) module unit, as this contains the radio module. Again, should be the same part whether you have DSP or not.

Great,

So now I only need to know which partsno.s have the aux-in possibility. Or is that visible on the radio unit??
Also, which cable is the best to use for the aux-in connection? (radiounit to car interior)
