Question about Garmin nuvi 750 GPS Receiver

4 Answers

Brand new Garmin nuvi 755t won't power up.

Received it one day ago, finally got it to lock into satellites last night(although it took a long time to find the satellites). Turned it off and unplugged it from car plug.
Went back out this morning, started car up, plugged Garmin back in, and NOTHING. No power, no nothing. The on-off button is not in "lock" position either.
Suggestions before I (angrily) send it back?

    Great. That should make for an interesting conversation. I hope they're open on Saturdays! Thanks.

    I didn't download anything. I simply plugged the unit into the car cig lighter and it didn't work. So I don't think a firmware update bug has anything to do with it. I've since returned the unit to the retailer, who will replace it(I hope).

    So when I receive the replacement nuvi 755t, should I download the latest updates BEFORE plugging the unit in and trying it?

I have had the same problem obviously. all i did was get a TORX TX5 screw driver and open up 2 screws. carefully lift off the cover(its just snapped in). Warning: battery and speaker are attached to the cover so do not pull the cover off or it will break the wire. carefully unplug the battery and leave it out for a 20 mins or so. plug it back in and it should power up and then connect it to internet, download webupdater and update. thats it and the problem is fixed.

HI, it is true just be careful when U remove the back cover not to disturb the 2 wires too much. Disconnect the battery and reconnect it 15 minutes later. reinstall the back cover.
Update to version 3.60. Thanks sherjatt!

This is not true...There was a bug in the latest firmware update that randomly came up that would download itself maybe without you knowing...it destroyed the unit....

Garmin Nuvi 755t Stuck in power up cycle


You can do two things.

First, plug the GPS in overnight in a regular USB charger. If the battery charges up, then the problem is with your Garmin vehicle cable.

If it does not charge up, you can buy a battery replacement kit for it: https://www.amazon.com/Garmin-Nuvi-755-Replacement-Installation/dp/B003VFSR4M

Can u tell me how to download free up dated maps for my garmin nuvi 660 thanks vicki


Hi Vicki, unless your nuvi was first activated and acquired satellite lock in the last 60 days (unlikely as yours was discontinued a long while ago) then you cannot get free map updates, sorry.

For models activated within the last 60 days Garmin offer a free update to the latest maps if the maps already on the product when it was purchased are an older version. After that, all updats must be paid for.

You simply won't find free map updates legally. Accurate maps cost a fortune to produce and update so nobody gives them away, even the few illegal downloads tend not to work and if they do work are likely to be out of date anyway.

The way that Garmin price their map updates, it's often better to simply buy a new Garmin with the maps pre-installed, although I appreciate that's not the answer you hoped for. If you do buy Garmin updates then you can either go for a one-off update, or for additional cost can buy a lifetime update, but it's limited to the lifetime of the device which is only designed to last three years anyway so may be poor value if you buy the lifetime update and your machine then dies of wear or old age.

Power the GPS down for a spell, maybe an hour or two, overnight if possible. This will clear the memory and then power it up again, let it reboot. Make sure the GPS has a clear view of the sky or use an external antenna so the GPS can gather satellite data. Also do not press the buttons many times as this can confuse the GPS and make it "lock" up.

755T runs slow have their been any noted problems that I don't know about


make sure it has a good charge on it...if the battery is very low, it will slow down or prevent the satellites form locking on

plug it in to the computer for a few hours, then take it outside in clear view of the sky and let it link up to the satillites.

to check of your unit needs any updates..go HERE and download the garmin web updater and after you install it, hook up your garmin to your computer via the usb cable provided with your unit.

if you need further help, just let me know

Garmin 755T - Same Problem


Have you tried a complete reset? If not this is what you do. Turn on the Garmin at the same time press the bottom right hand corner of the screen. this will return it to factory standard, but it will wipe out any information you may have stored on it.

Garmin 755T Issue - Firmware Update and acquiring satellite


Hi Bob,
You need to do a complete reset by turning it on and at the same time press the bottom right hand corner of the screen this will reset it to factory condition. having done that when you switch it on again leave some where where it has a clear view of the sky and leave it for about 1/2 an hour. This should sort it out for you. Best of luck.

Nuvi Blackout


This is a known problem that Garmin is fixing. Look at:

http://www.garmin.com/garmin/cms/site/us/support

Under "TOP FAQ" there is an entry for "My nuvi 755T, 765T, 775T or 785T will no longer turn on."

You will need to return your unit to Garmin for them to fix it.

Garmin Nuvi takes a long time to Acquire satellite


No. 98% of the time it took 45-56 seonds for your NUVI 660. Thats the compagny set up time acquisition and it did very well.

Be sur you had your flip antenna parallel to earth surface.
660 has THE BEST SIRF Chipset for acquiring satellite.

I had 2 NUVI 660 since 2 years. It work much better than those new 7xx series who it really took 2-3 minutes to acquire satellite.

Be sure you update your version to the last one.
