What do you guys think of this?
Has anyone retro fited Sat Nav, is it relatively easy to do. Might be a stupid question but will this unit replace your whole CD unit, if it does will you still have CD playing/radio function??
Does it have TV?
Depends on the year of your car, but the RNS-D is the hardest one to fit to an A4 from 2001-2008. You need to find a TMC module and extra wires from the cluster that are not in your wiring loom.
Much easier is the RNS-E DVD navigation.
You would need a CD changer with this RNS-D as it cannot play CD's, the RNS-E on the other hand can play CD's in it's nav slot and also play mp3 SD cards upto 4GB in each.
None of them have TV, it's always extra.
