I have this strange problem. Every once in a while, when I start my vehicle, the Z1 does not turn on. If I turn the vehicle off then back on everything is fine. I have checked all of the wiring and everything seems to be hooked up right. Temperature is about 70F to 80F so it's not too hot or too cold. I have found 2 other D1 owners that have had this happen to them too.

Does anyone have any insight into what might be causing this to happen?
