The Netherlands | Firmware 6.50 or 6.40 is for the TMX2050 and is also the precision IQ version.
For the GFX750 you should use 2.50 or 2.60.1. Version 2.40 was not good,had bugs.
If you updated above 2.4 you could not downgrade the NAV 900 anymore ,that is blocked.
Tell me did you use the 2.xx versions firmware?
.
Shut it down.
Disconnect all the power for 5 minutes .
Start the GFX750 again and wait till it is completly started and try to find out if it recieve any satelite and or the NAV
Shows up on the home screen.
If not try to intall firmware 2.60.100 again and wait long enough.
.
If it didn't work I am affraid that you interrupted the firmware update to the NAV 900 and that it is errased.
I am out of options , you should call your dealer.
Good luck | |
