How to charge Garmin 755t

My Garmin 755t does not turn on, only when it is plugged into my car. Battery is dead. Does it not charge when plugged into car? I only bought this back in March 2009. Can I not charge battery with usb plugged into laptop or usb charger? Thanks

I can't adjust bluetooth,there is no "bluetooth" icon.


The Nuvi 755T does not have bluetooth capability. See this link to see the specifications of the 755T from the Garmin website:
https://buy.garmin.com/en-US/US/prod14933.html
Bluetooth wireless technology No
You would have to have a Nuvi 765T to have bluetooth

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

I have a Garmin Nuvi 755T. I noticed that the unit was not charging via the car charger. I checked the charger and noticed that the green light was on. I also pulled the fuse and checked it and it is...


found female jack on the 755 mount where the car charger pluges into the GPS was not securely soldered onto ckt bd so after multiple times pulg in or unpluging the unit or just stressing the connection the fine wire conncetions (about 12) tend to break forcing the unit to operate on battery mode untill battery is discharged. you an purchase a replacement GPCCradle Holder compatible with Garmin Nuvi on Amazon GPS Cradle Holder Compatible with Garmin Nuvi for about $20

Car power supply for Garmin nuvi 755t does not work. Not sure if its the Wire, mount Adapter or other.


I assume you have checked the cigarette lighter to be sure it's working.
The most likely problem is the fuse in the power cord/charger. The plug which goes into the cigarette lighter socket has a ring at the end of it. Unscrew the ring, taking care not to lose any small parts, and it comes apart. Replace the fuse and it should be ok.

Internal battery won't charge


Common issue. Steps to troubleshoot/solve:
1. Pull off face, press reset tab.
2. If unit wont turn on or if turns off immediately, connect to home computer using mini usb on side of gps (any usb cord that fits will do). This will charge the internal gps battery, which is discharged.
3. You will not be able to see the gps charge indicator while the usb cord is plugged into the unit. To check charge level, disconnect it, turn it on, and note the large "battery" icon.
4 Do you have a dead internal battery? If the gps holds a charge from your computer usb port, you don't.
5. If you have a dead battery, Google DIY replacement. With some soldering it can done for $15 total.
6. If you don't have a dead battery, the issue is charging from the cigarette lighter socket. Your car socket may have blown a fuse (check car manual). Your charger unit may have blown a fuse (unscrew the tip, check fuse inside). Also, some car sockets don't work when the ignition is off. Test yours.
7. There is a good chance the connection of the charger wire to the gps cradle is the problem. Fiddle with that. Replacement cradles are available for the c340 at about $25.
8. If your unit is not charging from the cradle/socket, buy a 12v usb cord. Plug into socket and into usb port of the gps. This is a workaround or alternative to buying a new cradle.
9. IMPORTANT: observe the "battery" icon while driving, esp. if you have doubts about charging. Basically, if you can see the icon, you're not connected to an outside (car or computer) power source. That is, if you can see the battery-charge indication, it means your battery is currently discharging and unless you get another power source to work it will be dead in a few hours.
