This article compares features of the RNS 315 vs. RNS 510 navigation systems with the stock RCD 510 6 CD changer radio standard on TDI. If you buy a Golf, Jetta, Sportwagen, Tiguan, or Passat without it, you can also retrofit the RNS315 or RNS510 after you buy the car by buying it as a part and swapping the radio out.
