Not a bike related issue (yet), but i bought a new V1 last week (well new to me) and it was falsing from EVERYTHING. Always on KA band as X and K are disabled. Drove me insane, but thanks to some help at http://www.radardetector.net/GRRR---...ing-16935t.php this is now fixed.

The radardetector.net forums have a small motorbike section also...
