Jim,
Man oh man!
I've seen this B4, but you forgot the most important part !! No pix of
the D700 APRS and other radio inside views.
I agree that the power off timer isn't the solution, but didn't catch where
they powered it from [[ battery dip, or full crank power-off cycle]] . It
seems like an extra battery (a couple of AH), a couple of power hot-carrier
diodes, a resistor (to float-charge the extra battery) and possibly a
(capacitor/diode held, slow drop-out) power on/off relay is a lot cheaper than
the $80 mobile 10 A. UPS.
BTW. My D700 always re-boots cleanly from the crank interruption (when powered
off a cigarette -lighter-like 120W. power port). ...don't know about a
battery-connection crank-dip. Haven't done that on the new car yet.
So did they blow it on the D710?
73, Steve
