Pioneer DEX P99RS.
I have had this unit in my car setup for about 18months with zero issues - today I reset the clock to allow for daylight saving hours - all good, off I went and everything was normal.
Come back home, park up, take the face-plate off as normal.
Go back out to the car about an hour later, put the face-plate back in as normal - and NOTHING.
I check the 2nd battery - 12.9v.
I check the two circuit breakers (one at each end of the split charge) no issues.
There are no fuses in the circuit, just circuit breakers and they are all good.
Headunit is not switching on.
Press the reset switch on the headunit - nothing.
What am I missing as this is weird and has never happened before as I cannot power up nor can I take the face-plate off.
Any and all suggestions appreciated. Thanks.
