Released in February 2012 by Garmin. The Garmin nuvi 2555 LMT has a 5-inch dual-oriented display, Bluetooth capabilities, lane assist, 3D traffic, and Guidance 2.0 software.

My GPS Reboots unexpectedly very often

My GPS always shows "lost external power" and reboots unexpectedly. But the cable works fine for my other Garmin GPS, and I reset the device to default, Still not working.

Please help, thank you!

Thanks for your reply,.

Yes, it's an original charger which works fine with my other Garmin GPS.

I think that's the problem of mini-USB too, any recommendations?

Thanks!

you can try to open the gps. i did it before and its not hard to do.. check the main PCB for the charging mini usb. when its loose you will have to solder a new one. check the cable's as well. cause i had a molten cable of the battery...

It is possible that the mini-usb connector on the back of the Nuvi may have failed.

Test the connector by gently wiggling it. If it feels loose, it is a an indicator that it may have become disconnected internally.

Is the red light from loading still on when shutting down and reboot?

It is a common problem to this GPS.

Is it an Original charger and cable?

Kind regards,

Kevin
