I installed a Z110BT into my Miata about 3 months ago. This was a 2nd install - I had it in my previous car. So I bought an aftermarket power harness (non-Pioneer) and AV harness to do the 2nd install (all the other wiring was stock). I have had zero issues with the AVIC up until about a week ago. I am experiencing a temp drop in sound (complete loss - not a mute) where I will lose sound for about a second, and then it will come back on. It does this randomly and doesn't seem to be related to the unit heating up - although it is fairly tight back behind the stereo. It will do it a few times in
