Pioneer DEH-P690UB FM tuning problem
Pioneer have factory set your DEH-P690UB to 0.2Mhz steps to match the American FM frequency allocations.
The fix is not casual as it requires complete disassembly of the head unit and repositioning of two surface mount resistors.
This will void any warrantee and unless you're good at microscopic soldering could also ruin the set.
I did however void my 2 year warrantee yesterday partly out of frustration and because I have the right SMT tools at work.
Now my tuner CPU thinks it's in the Austrailian/Asian model DEH-P7950UB and is also compatible with UK stations.
A previously hidden menu is also available where I can set either 0.1 or 0.05Mhz stepping for FM and 9 or 10KHz for AM BSM scanning.
The rotary control now steps in 0.05's instead of odd 0.2's on FM
Hope this helps.

I have the pioneer super tuner 3 DEH-1900MP. My
I have the DEH-1200MP model super tuner 3 and it would not power up after battery died and was jumped. There is a fuse at the back of the stereo that I unplugged and plugged back in and then the stereo powered up. I had already checked all of the other fuses. Took me a while to figure this out.
