I have a V, an ‘old model’ VI and a ‘new model’ VI. I have never had a problem with any of them, nor with another ‘old model’ VI, which I sold to another forum member, nor with a V, that I also sold.
There is a really good GPS support section on UKGSer where this entire thread should be moved to, as it has as much to do with WC engined BMW motorbikes, as I do with Morris Dancing or buggery.
