Anyone who's been following the S Type forums can see I've been trying to do research on getting a Kenwood GPS/NAV unit installed next weekend. The time has come and gone for me to actually make the purchase and I'm still not sure about which unit to get. I'm stuck between the Kenwood DNX5120 and the Kenwood DNX7120- I don't know enough about headunits to know whether all of the "extras" on the 7120 will be exactly necessary. Originally I was planning on getting the DNX5120 but it said something about having 2 RCA outputs and not 3 like the 7120 and few other things. Does anyone know enough about the two different units to tell me whether or not I'll have any particular issues with one vs the other?
