off topic but when i would ride my streetmate my mp3 (zune) would shut off. I would be listening to it, then go and start my moped, and as i did (still holding my zune in my hand) it would freeze and shut off! wtf!!!
but i had the same problem trying to use a wireless, digital speedo with my white tomos, when the bike was off the speedo worked then as soon as i turned the bike on it stopped working.
