For those that keep odd 302 facts in a file somewhere....

Over the winter I took my instrument panel home to putter. About 3 months later I turned on the unit and found the the 302 would cycle its start up tones over and over again for minutes before getting to the "set pressure" screen. I ultimately found that it had to do with the GPS. I had cleared the memory on the 302 which, I assume, also cleared the last know GPS location. So the 302 had to start from scratch to find satellites and get a fix.... plus I was indoors at the time. Once outside and a fix was made, startup now happens normally.
