I have seen discussions in a few places on similar problem. I start up normally and get green lights with 11 or so satellites showing. I do a compass calibration and all goes well until the end then get all red lights blinking. They never go green even with 11 sats showing. If i power down and back up and not do a compass calibration the green lights show up and off I go. This did not happen ever with 3.08. Any ideas??? Thanks!
