Okay so I have an alpine kce-350bt bluetooth unit. The problem is it was working before and stopped working yesterday. I deleted the unit off my phone list of trusted devices and deleted my phone off the list of paired devices. I tried connecting on both, it won't find my phone on the unit and visa versa. Is there anyway to fix that? I tried using my friends phone which found the device and than I tried connecting them and the phone would say connected but the device would just say connecting for a while than the phone would no longer say connected. I'm gonna take it in to where I bought it tomorrow since I think it's the unit. And neither will find either now, any help would be appreciated
