I currently have an Alpine INA-W900BT installed in my truck. When I am listening to it the radio will randomly shut off driving down the road or sitting still. I haven't been able to associate any patterns with hitting bumps, or pressing my brakes or anything to determine a pattern. It seems to be doing it at just random intervals. Some trips it will work just fine the entire time. I took it into the shop that installed it and had them check it out and they told me that it is a bad module that interfaces the head unit with the Bose Premium system that came stock with the truck. Has anyone had this similar issue, if so is this the correct cause, or not? Also, it does not seem to be heat related because the unit will shut off at times as soon as the truck is cranked. Also, I don't know if it is just be, or it is true, but it seems to happen sometimes around bumps, or when I get on the brakes. But like I said, some times it will do it without the truck even moving. Thanks for any help.
