I retro fitted an RNS-E system with factory bluetooth to my 52 plate quattro a couple of years ago now, however I am toying with the idea of upgrading it to a newer unit as fitted to the current A3, mainly from the point of view of having the LED screen and the ability to use SDHC cards as the new units will handle up to 32Gb if I remember correctly.
Obviously I would need to swap over the fascia's (how difficult is this??) but what is everyone's thoughts? Is there anything else a newer unit would add such as voice control? (I do not have a multi function wheel on the car) Should I go for a specific version number??
Cheers in advance
