Everytime I power up my GNC355 (same navigator as the 175 and 375), it still thinks it is at the factory in Kansas. Consequently it takes longer than my Dynon unit to acquire a GPS signal. For some reason it does not remember it's last known position. Any ideas? Thanks.
+1 Brian! I've been immersed in the GNC355 Install Manual for the last few days planning my own 355 installation and I wholeheartedly agree with your assessment and suggestions to JPM757.These new units from Garmin have a little config module that is a small circuit board you plug a 4 wire harness into one of the back connectors and you put it in the connector shell. These modules are the place that stores your unit setup settings, so if your unit is replaced, you still have your settings. It might also be where your last position is stored.
So was the config module installed and correctly? If not, check that out. Yes, it can be a bad internal memory battery, but being new, that is a slim chance, but possible. Good luck.
I'm new to the forum and don't want to hijack JPM757's thread but I am curious Brian, if any of the six GNC355 installations you've done have interfaced the GNC355 with a GTX335? If so, I'd like to ask you a few questions either here in this thread if appropriate or perhaps in a new thread or in a Private Message.I have installed 6 of these units and never had a problem, but the first time it does take a bit before it gets a position lock on, so until it does lock on, it will still think it is back in Kansas.

Please let me know! ZT
