The “debug menu” (also called the “maintenance mode”) on a Garmin Nuvi 750 is a utility that allows you to reset your device back to factory settings. You can reset any addresses saved to the device as well as custom points of interest, such as restaurants, hotels or whatever. You don’t need to do anything special to enter this menu on the device, you simply just need to press in the right location at the right time.

Updating your Garmin nüvi GPS unit software just got easier. Use WebUpdater to automatically keep your operating software current. The Garmin WebUpdater can be downloaded from Garmin . If you need to update your software / firmware from Linux , you can actually extract the downloaded exe and upload the unit software / firmware update file (e.g. called GUPDATE.GCD) manually to the device. The Garmin Firmware downloads are available from Garmin .
