2005 H2 Navigation System, GPS Clock and Date won't sync
Installed the Isimple GM575 IPOD adapter and HD Radio. Navigation system re-calibrated from default location to home, and GPS clock will not sync. Can't find my Navigation system Manual anyone know the Process to force a GPS Sync? I thought it updates automatically. Maybe it takes time? Don't know.

Auto GPS Update: With this feature on, the navigation system time will be set to match the current GPS
time. The time will be updated with the GPS time when the ignition is turned on. You may also touch the Off
screen button to turn this feature off.

I disconnected the Battery for 15 Minutes and reconnected the Clock finally Sync'd. Had to calibrate the position. I'll see when I start it in the morning if it holds.

OK Time sync is fine, the date is Jan 1, 2000. Just a little off. Hoping next time I drive it the Date eventually SYNCS.
