2004 Garmin. tempermental to turn on.
Got it to work 10 times in a row by ensuring it was the very first power activation on the battery: Religiously turned off all switches, turned off dock power and it worked until now - and has failed last 5 times using this process. clearly a power issue but Garmin wants a minimum of $450 to diagnose with no guarantee. could go with newer cheaper model but like the 8" size....thoughts anyone?

You have to take a very methodical, baby-step, approach to troubleshooting electrical problems.
Replace the inline fuse. Test. If it passes, then:
Remove the power and ground wires from the boats power system and attach to a separate 12 volt source. This will eliminate the unit from the failure chain.
If it passes the separate 12 volt source test, the problem is in the boat wiring.
Report back
