Nuvi 750 DEAD

 

Help!!! I was in the process of showing my daughter how to use my 750. She turned it off accidently. Now it is dead. It will not do anything. I tried to plug it into the computer to see if it shows it being recharged. Absolutely NOTHING. Any ideas. As always, thanks to all.

Is there a way to reset this

Is there a way to reset this unit? Maybe that will help.

To reset the unit, slide the power switch to the far left ON position and hold it there for 15-20 seconds to reset the unit.

If the unit still does not power on, try to recharge the unit by connecting it to your PC's USB port and charge it overnight. Be sure your PC does NOT enter any type of sleep or power savings mode since this will cut off power to the USB ports and will stop the charging process.

O... not good!

What were you doing when it was turned off?

If you were updating the map etc, the device could be very angry. as someone said resetting works often. If that doesn't work, see if your computer recognizes the device when you hook it up... if the computer doesn't know what the device is, or it doesn't connect correctly, I would call support.

If it connects to the computer, it may not be serious.

My old TOMTOM had a similar problem (only it was my nephew!). It was getting updated when he pulled the plug. They walked me though a firmware reinstall, and it was FINE!

Another time a friend of mine gave me her TOMTOM and said 'Make it work...!' That one locked up and wouldn't connect to the computer at all... hers needed to be replaced!

At work I am expected to fix everyones computer... and I guess they figure GPS's and cell phones are computers... NOT THE SAME!

Recharge....

Instead of the USB from the PC, try using the normal plug to recharge.

Worked for Me

Using the AC plug worked for me with my Nuvi 660 in a similar circumstance.

Try charging overnight

If you haven't already done so, try charging the 750 overnight. If the power is completely drained, it may take some time before the device "wakes up".

Good luck.

Just happened to me

My Nuvi 350 went black while using it. Read Jim's suggestions for dead gps on sharcnet. Tried plugging in gps to pc, to car, to wall, held reset button and on button, so lucky my gps turned on.

Go news, older garmin units have reduced out of warranty flat rate repair, my unit would have been $39.

Battery might be dead.

It sounds as if the battery's gone completely dead. As others have suggested, plugging it in and letting it charge overnight via its USB port should do the trick.

They are other threads on this forum about replacing the internal battery, should that be necessary.

Let us know what happens!

Battery replacement

The good news is, if it's the battery, the thing is easy to replace yourself. I replaced the battery in my nüvi 760. Same unit as yours as far as battery replacement. There's a simple video on youtube that shows how.

Nuvi 750 DEAD...

To reset... Press and hold the on/off button for 30 to 35 seconds. If that doesn't fix the problem:

If you bought it within the last 30 days, take it back with the receipt for an exchange where you purchased it.

If over 30 days old but less than one year... call Tech Support at Garmin for a repair/replacement.

Over one year... Call Garmin Tech Support.

I am assuming you are the original/registered purchaser of the unit.

Check The Battery

I Believe it's a battery issue, replacing it with a new battery could resolve the issue..

Why not buy a new Nuvi?

With Nuvi 265WT down to $130, just buy a new unit.

Unfortunately, the 265 is a poor substitute for a 7X0 navigator.

Given the choice between a FREE 265 or a $39 repair to my 760 I would pay the extra money for the 760 (yes, I know the OP has a 750 - I suppose he doesn't need Bluetooth).

It's baaaaaaack!

Two hours later it starts working again. The battery was fully charged when it "died". I really have no idea why it it stopped working or why it decided to "wake up". I did not reset it. It has worked fine ever since.
(Someone asked if I am the original owner. I am).

Thanks to EVERYONE for your imput.

For what ever reason. I

For what ever reason. I believe I would still do a hard reset.Back up favorites if you do.

Do the 7x0 units suffer from

Do the 7x0 units suffer from the problem with flaky power switches? Just a thought....

Good to hear.

I AM NOT SURPRISED

A problem that has been found in many Nuvi's

Not surprised either! It's a Nuvi.

This is a common problem with the Nuvi series. The on/off switch is a surface mount switch that is mounted off of the main PC board.

The problem is, that there is no support behind the switch, so when you press down the button, the solder leads of the switch are stressed and eventually break off the main PC board. This is a design flaw and could have been easily prevented by wedging a small piece of plastic between the rear of the switch and the SD card housing to give the switch support.

1. In order to repair this problem, you need to have surface mount de-soldering/soldering skills as well as the appropriate soldering tools and case dis dis-assembly tools. Without these things, you take the risk of further damaging your Nuvi, possibly making it impossible to repair.

2. Re-soldering the switch is not going to resolve the issue long-term. In some cases, the switch can not be re-soldered and additional rework must be performed.

3. In order to fix this problem once and for all, the switch needs to be mechanically secured better to the main PCB using pre-tinned buswire. In addition, a custom-fit piece of plastic needs to be glued behind the switch to give it additional support.

If you don't want to do this yourself send out for repair to a reputable repair facility such as:

The power switch problem and it's solutions mentioned apply to the nuvi 3xx/6xx series which uses a totally different switch design (push on/off, mounted directly to the main PCB and unsupported as described). the 7x0/7x5 series' slide switch mechanism slides within a supported slot within the case itself, unlike the 3xx/6xx. The OP's issue was with the 7x0 series, not the 3xx/6xx series

The 750 was my first GPS (paid $500.00, but that is another story). When I turned it on I found it difficult to understand the way the slide switch worked and at first thought it was a defective unit. I was expecting to feel a click as I moved the switch. Now turning it on/off or resetting is a snap (most of the time).
