Help, route disappeared after power off

 

I have a Nuvi 750. Recently I found out if I stopped somewhere before destination and turned off the car, the route disappeared after I turned on the GPS again. Anyone else have the problem or know how to fix it? I called Garmin and they could not help me.

Nuvi Looses Route information when powered off

I'm not an expert, but it would seem logical the route is based on where you started and where you were going. When you turned power off, that information was erased from the 750's memory so when you turned the unit back on, it had no idea where you started from or were going. Kind of like having a program running on your computer and then cycling the power on it. It has no idea what you were doing and may or more than likely will not let you recover the same information.

For a more technical description, route information is stored in volatile memory and when it looses power the information is erased.

Source of route

Was the route downloaded from Mapsource or was it a saved route created in the Nuvi?

Either way, after powering up the unit, restart the route (Where to?, Routes). It should ask if you want to continue navigating the previous route.

My 880 keeps the route information

I just tested this out sitting here at my desk. I had full satellite signal by the window and asked the 880 to map from where I am to another city. It calculated the route and stated "please drive...". I powered the 880 down for one full minute and then powered it on. It then stated "please turn at..." and displayed the same route that I asked for prior to the power down.

So clearly the information is not erased when you turn the power off on the 880. Are you saying the 750 is different?

Battery ??

Does it run OK on the internal battery (only)?
If not, you have a battery problem of some kind.

If YES, then try unplugging the car power before you turn the car off, to get it on battery, and then power it down by pushing the switch.

Powering down with the switch may be different than a power LOSS when the car goes off.

nothing to do with the battery

Should have nothing to do with the battery. When you turn off the external power the Nuvi's shut down automatically in 30 seconds unless you tell them not to.

I would also ask... Is he running a multi-stop route? That may work different from just a single destination route. My 260 only does the single destination and it remembers even if shut down for hours in the middle of a route.

If the battery is DEAD, when you turn off the external power, it will shut down automatically in ZERO seconds, whether you tell it to or not !!
