Gurus,
I got ahold of an old Garmin GNS 430. When I install and power it up, it is in test mode. I referenced the Garmin maintenance manual, and it says, to put the unit in test mode, ground pin J1-76. However, I can't find where that pin is or how to ground it. I'm not an electronics guy and the only manual I could find does not have detailed instructions on this procedure.
Can someone tell me how to get out of test mode so I can see if this unit is worth keeping?
Thanks,
Chuck
Edit...
I have also installed another 430 unit into the same rack, and it works perfect.
