RV760 will not start

 

Used my RV760LMT about 2 weeks ago with no problem. Took it out and brought it inside, like usual. Last week downloaded tracks with no problem.

Today I tried to turn it on. I get the GARMIN splash screen, the copyright screen and Loading Maps. It then shuts off. Does this by itself just pushing power button, also does it plugged in computer or docked and in vehicle.

I have tried holding power button to reset but it just seems to do the same thing over and over when doing that.

Any suggestions?

Thanks
Ray

Charge battery

Leave it plugged in to the computer or a battery charger for a while,so you can get a good charge on the device battery.

I am trying that but it constantly tries to reboot when plugged into any power source.

I have tried to turn it off

I have tried to turn it off while attached to a power source. it just keeps trying to restart. If I hold the power button, I get a pop up saying Power off or cancel. Both just have it restarting again.

Try the following...

Sounds like you may have a corrupted map file.

See the post by me, third post down from the top. In that post, follow the link and read the second message by Boyd. I've had the same problem and Boyd's discover helped me boot the unit to repair the corrupted map file. It's tricky to initiate but it did work on my unit (nuvi 3790).

EDIT: Looks like you've already tried the procedure I linked to.

Noboday mentioned this but do you have a memory card in the unit? Remove the memory card and see if the unit will boot with it removed.

Wall charger

Had a similar problem with a Drive unit.

Plugging it into a computer is not the best idea, that is a low power source.

A wall outlet charger is a better option.

I just let it keep rebooting overnight and by morning it was on and at about 1/2 charge.

I think it must not have been shut down and the battery slowly drained while it was in sleep mode.

Sorry to say that I have

Sorry to say that I have tried it with and without the SD card. Thanks anyway.

I did leave it plugged into the vehicle for an hour with no luck.

I will try the wall outlet overnight.

The battery did not have enough charge to do a complete boot. Everyone should have a wall charger to deal with problems like this.

Agreed

Yup, overnight charging with almost any indoor charger is likely needed and if a charger is marked as 1A or 2A, all the better since most computer USB jacks only offer 0.5A. If going out for a drive, a charge via the Garmin cord to the vehicle's power outlet (which I still want to call a cigarette lighter socket) will go faster than many indoor chargers.

Given the OP's statement that other than for downloading tracks once, the GPS hasn't been powered up and charged for two weeks, try a full charge before researching other potential issues since a very weak battery can cause so many odd issues.

I do wish Garmin would set the default power switch setting to Off rather than Sleep.

Yes

I just used my 2a phone charger that has a usb port and the Garmin usp cable. No need to get another charger. If you're leary about using 2a than some of the older phone chargers are about 1.5a. But 2a is just fine.

I too vote for the unit shutting off. OK, so you have to turn it on again when you get in the car, but that's minor compared to this problem and inconvience.

2 amp 3 amp or whatever, it only takes what it needs. Similar to you going to a buffet, unless you're a glutton.

Device problem

You may have already tried this,but try what they call a soft reset. See https://support.garmin.com/en-US/?faq=TiDz048p5C6qe2dMv5tNU7... .You will also see a video within the link for a on hands demonstration .

I think it might be dead.

After 8 hours on a 2A charger last night and 3 hours today on the actual car charger (plugged into a continuous power socket) it still does the same thing.

I think I might be running out of options.

I've tried the chat function

I've tried the chat function on the Garmin support site. All that has gotten me is a Retrieving Config - Please wait popup.

Last resort

One thing you can try as a last resort is to open the case and unplug the battery. Leave it unplugged for at least 30 seconds. This will allow the RAM memory to completely reset, unless it has non-volatile memory. It's possible that something got corrupted. A "cold start" may remedy that.

Just a thought.

I think I may just do that.

I think I may just do that. Just have to get a torx driver small enough.

Have a look...

Have a look the unit's battery replacement video just to make sure there aren't any delicate flex cables or other things to watch out for when opening the unit.

And if still no luck, it may be worth a $34 battery replacement if the original battery has died.

Good to see you at The Factory again, Dorkus...

Device problem.

Since you have tried most everything so far. Why not call Garmin. They have always been good to deal with in the past. Maybe you can get a replacement model with little or no cost. Worth a try.

Tried that, no difference. While I was in there, I checked the battery, it had a solid 3.95V, so that's not it either.

Thanks to everyone for their suggestions. But it's probably time for a new one. I've had it 5 years.
