I can heartily reccommend this 65 channel GPS receiver unit to complete the ensemble (thanks syncro Doug!) It's got a nice strong magnet built in and sticks to the top of the dash by the windscreen nicely. Really fast satellite aquisition, quicker than my Tomtom anyday:

Arrived in 3 days from sunny Berlin and the seller even asked if I had a VAT number for the invoice!
Happy navigation, wherever you're going
