RNS 510 Bluetooth playing up with my phone

Any tips on a type or where to look

I recommend 9W7 and I suggest searching eBay or keeping your eye out on the various VW forum classifieds sections. Avoid earlier models as they have limited Bluetooth functionality. There is also the later 9WZ that, as I understand it, has inherent connectivity capabilities, but I know little about it so cannot say much more than it exists. Here is a guide you might want to look at.
