I recently installed a alpine stereo with a capacitive touch screen and noticed the other day that the touch screen intermittently does not work. By not work I mean the controls of it, it still shows things, plays music and whatnot but you try to adjust the volume or change songs or anything like that and it just acts dead. I could be wrong but it seems to only happen in the morning, when I start my truck up in the afternoon after work everything works fine. Crutchfield has instructed me to take my multimeter and check to see if the stereo is getting a a full 12V when powered up and I will check that out tomorrow morning. I was wondering 1: if anyone’s experienced this before 2: if it’s a truck or stereo issue 3: where do I check the voltage, at the base of the power cable that connects to the unit itself?
