I hvae a 2001.5 A4 w/ Symphony radio. I was searching the site for the differences between the RNS and Navplus versions. Can someone give me a quick rundown or point me to a knowledge base?
I know there's a way to retrofit the RNS version, but would prefer something that fits w/o modifications. Is the RNS version worth the mods associated with it?
How hard is it to do the TV tuner? How much should I expect to pay for each unit?
