I've just got my hands on a mk5 1.9 tdi 105 2007 and I'm looking to improve the look and performance of the car. my brothers a mechanic so I've got the tools. but I've no idea where to start. I'm looking at replacing the standard radio with a sat navigation but would like the Bluetooth how do I go about this been told the rns 510 but it doesn't come with Bluetooth . Also anyone know a rough price for a remap from rtech? also what else would improve the performance induction kit etc? Cheers guys
