My Garmin Nuvi 52LM will not turn on when I start the car with the cord in place.

1. Make sure that the charger outlet is supplying +12VDC. Try another device by plugging it into the outlet and seeing if it powers on.

2. Make sure that the fuse in the charger tip is not blown. The tip usually unscrews. It is spring loaded so be careful that the fuse, spring and power tip are not lost. Check the fuse. It should read 0 ohms with an ohmmeter. If it is glass hold it up to the light and see if the wire inside is open (broken). If the fuse is bad, replace it with the same value.

3. Make sure that the charger outlet is controlled by your ignition. If the the unit is on all of the time, regardless of the ignition setting, then the outlet is wired directly to the battery via a fuse.

4. Does the unit power up on its internal battery? Is the charger working? If it is bad, the unit will not power up when plugged into a 12VDC outlet.

I was trying to straight wire my GPS.

You may have inadvertently blown the fuse to the cigarette lighter on the truck, I would check there first before doing anything else

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

Charge Problem

Hello guitarman249,

It sounds like a bad battery. Theoretically, it could be the charger but if the red light on the charger still comes on when the unit is plugged in then the battery is the more likely culprit. The only way to really know for sure is to try charging the unit with a different cable, such as the USB cord used to connect the GPS to a computer. The GPS should charge when connected to USB. If it doesn't, then it's the battery.

Like most GPS receivers, the battery on this one is not replaceable by the user. If you do determine that the battery is causing the problem you will need to contact Magellan tech support to arrange a battery replacement.

Best Regards,
"Go Ahead. Use Us."

Try to mount the gps antenna on the roof or front mirror where 2 to 3 satellite can hit it at once. Goodluck.

Keeps blowing fuses

It has a short in the wiring which is "not user fixable". I think the wires are crossed. Take it back, they need to repair or replace it. I suggest you replace it. Take the GPS with you show you can show them the problem. If you bought this on line call Lowrance and find the nearest repair center. Repair it yourself and you loose the warentee.

Gps not working

I know this may sound funny but replace the water temperature sensor cable that's connected to the unit. There is a module in the temperature sensor cable that has been going bad on a lot of these units recently. I had the same problem and replaced the temperature sensor cable and that fixed the problem.
