Mine stopped working last night. I can still use the head unit controls on my Alpine CDA9886M, but the handlebar controls (both sides) don't work at all. I pulled the fairing off, and checked the wiring - its all still tight. Checked the LED on the adapter, and it doesn't flash a code when you power turn on the radio. I am assuming it's broke, but I figured it would check and see if anybody else has had problems with one of these...
I hope so - a replacement costs $170! I already emaild Hawgs tech support, but haven't heard back from them yet. If I do have to get a new one, I will go biketronics because of the warranty!
