Question about Magellan Roadmate 760 GPS Receiver

Won't Power On Anymore

I have had my 760 since December and LOVE, LOVE, LOVE it! I use it a lot, even around town. I tried to use it the other day and it would not turn on. The power cord is lit, but the unit will not turn on. I'd be very disappointed if my unit is broken, as you know they are not cheap. Please advise. I have unplugged and replugged - nothing happens. I live in Florida... will the heat bother it?

Re: Won't Power On Anymore

I've got one that has a problem with the power connector. Look on the adapter thingy -- with a pin, wiggle the center power pin. If it is loose, this is the problem. Carefully use a knife to open the adapter thingy (it's glued together). Go to Radio Shack/Fry's and get a replacement power female socket that solders to the little PC board in the adapter thingy. This will fix it. Allen

Re: Won't Power On Anymore

Works great when it works. They are also know to freeze up. People have reported that it only works up to 6 months then it won't turn on. Even worse, tech support is few and far between and it seems nobody knows how to work on them. You can send it back to the manufacture to have it repaired under warranty, but don't look for it anytime soon. They will hold on to it for months. For me, I use a road map, It never stops working, and its always in the glovebox.

My magellan 760 doesn't acquire the satellites anymore. I already pressed reset gps through diagnostics but still doesn't work.

Hey lluny,
Good to hear you've already tried doing that.
There's a silver/black (diff. models = diff. color) cable inside your unit that sometimes comes unplugged. You'll see it as soon as you start opening your unit. So soon that you'll want to be careful when you are first opening. Make sure it's plugged in securely, I'd even unplug it and plug it back in.. but that may be risky & put too much pressure on the base solder. The last thing you'd want to do is permanently damage your main board.
Let me know how this works out and if you have any questions. If you do attempt to pull the cable to unplug/replug try to squeeze gently

My nuvi 760 doesn't play sounds anymore - through the speaker or through the earphone jack. I deleted some mp3 files a while back and I wonder if I accidentaly delted a audio driver file. I'd like to check...

No, there ar no audio drivers. If you use the headphone jack a lot, it coul dbe that the headphone jack has broken loose from the board. The headphone jack also controls audio to the speaker. The headphone jack must either be resoldered to the board or replaced. Please see this link:

Nuvi 760 will not turn on !!

I just had the same issue, after using the unit for 11 months.
WOULD NOT power on... and i freaked.
This is what solved it, no matter how strange it sounds...
I held the 'power switch' to ON for 20 secs, then it came on again.

I hope this works for you as well!

Voice prompt and more

First go to Menu > Tools > Settings > Language (icon is red lips)

You will see three settings: Voice, Text, Keyboard.

The voice setting may be blank. That just happens. Touch and be sure to select "American English, Jill or Jack, TTS. The "TTS" is very important in that it causes street names to be spoken. Example: "Turn left on Main Street." If you choose a Voice Language that is not TTS, as are the first selections shown, you will get commands without street names. Example: "Turn left." but it won't say the street name. After you have done this the 760, and maybe other models of the nuvi, will lose this setting on a random basis. Everytime it goes silent you have to redo the process of setting up the voice language. Who knows why?

Turns off when i move the gps slightly.....

I'm going to guess you need a new cradle. The pin inside mine broke off in the female end of the car adapter, resulting in no power. If it's loose & periodically making contact, it would power on & off before finally going off for good. Cradles can be had on ebay for around $20.

Garmin Nuvi 760 Frozen


Have you tried reading the manual?
Availlable here:

Suggest you try the following:
Holde the on/off switch in the on (left) position for 8 seconds, then release.
The unit should now power up as usual.
It worked for me!

Good Luck!

Magellan 760

sounds like your power dock is the culprit, not the internals, you can purchase one from circuit city or tigerdirect.
