I used the German E-bay to buy the Bluetooth module & cabling for my RNS-e, cos it seems hardly any UK specification cars had the bluetooth module fitted due to Audi charging extortionate rates for this optional extra so hardly any available for a reasonable price in the UK .....biggest problem is that most German people using the German E-bay dont like using Paypal....they prefer direct bank transfers....I am lucky though as I work with Germans who can translate for me...and have offered to pay the German vendor for me and I pay them.
For my Bluetooth module, I managed to convince the German seller (via a Bable translator) to increase his postage costs to cover the Paypal costs..so no problems....only thing I did worry about was that I was going to get stitched up with a faulty item....fortunantly it works brilliantly !
Lastly the current (April 2009) exchange rate is bl**dy awful !
