just eventually got it fitted and workin this morning, so not really had a proper play about with it, it was quite expensive, but my other option was the RNS510 which everyone has, and by the time u get the module for the ipod, and bluetooth, its probably not that much more expensive. plus its more expandable than the RNS
I am not sure if any1 else on this forum has it, so could be a little more rare.
Will have a little play about with it, and see whats what and maybe right up a review on it. have never used an standard VW satnav so wont be able to compare it.
