I just installed an Alpine 125BT in my truck, 2002 GMC p/u truck, along with the Alpine KTP-445 power pack amp. All functions work great except the microphone while using blue tooth calling. I can get my Droid X to pair fine, make calls, answer calls, etc. I updated the 125bt firmware to 4.0 successfully. I have the mic input set to 7, the highest setting. To trouble shoot so far I have connected the mic that came with the head unit to my cp, it did not work so I grabbed another mic that worked with my cp fine. I hooked the working mic up to the head unit and nothing. If I scream into the mic you can barely make out what I am saying on the other end of the phone. Am I missing something or is the HU trashed internally?
