Thread: Nuvi Pre-boot Mode

This is normal, nuvi waits for about 30 seconds in pre-boot mode, if you don't start flashing in this time, it goes to calibration procedure.

Hi, windows 7 stills cannot detect it as a usb device. So how to flash?

Don't you use updater.exe? This program should detect device in pre-boot mode.

Thanks....The gps finally can be detected by updater.exe.

Caty, I did set the gps in storage mode. Cannot find such setting in diagnostic page. But anyway, Kano's instructions helped. The gps is detected in the updater.exe for flashing.

Thanks to both of you!
