I did not know that HID interferes with the wireless. We don't plan on doing any nite riding - well definately not my gf.. I just put a NiteRider cheepie LED front/rear lights on her 7200 for my peace of mind.
In a way I hope she doesn't like the looks of the Astrale 8's wires so I can put it on my 1000. It's got more stuff than she cares about (like speed, cadence, etc..) she just wants to know how far she went but she won't let me strap my little eTrex vista GPSr on her bars...
