Hi Folks,

Total newbie to the VAG/VW world. So.... I have just picked up a 2007 VW Touran which still has the original head unit in place and searching on Google seems to be the RCD300.

I want to upgrade this to something that has Bluetooth and DAB, with the head unit being a tad low sat nav is not really required. Now I would like to try and stay stock, however if this proves too expensive then I'm happy to go with an aftermarket.

I have seen a few stock units being advertised on ebay which could possibly be within budget. However, scary part, I have also read on the web that these will/can cause battery loss. How and why is my first question and secondly does this also apply to aftermarket units?

Thanks

Saul.
