My navigon 7310 will not turn on or show the charging icon when I plug in the usb connection charger. The light at the bottom of the navigon will come on, but navigon itself will not power up. I have held the power button for 15 to 20 secons. I have depressed reset button for at least 16 to 20 seconds as well.

Try turning it off and turning it back on while it is still plugged in and see if that works.

SOURCE: Tomtom go 730 will not power up.Brand new,used a coupla weeks.

you need to do a hard restart. find tiny hole on under side by bracket mount and press it with a tiny paper clip once. you have to look very very close to see it. you can also try to hold down on power button for 5 to 6 sec.

some chargers will not work i think somwthing to do with a micro chip in it.

SOURCE: garmin nuvi 5000 wont turn on.

Your nuvi 5000 does NOT have a internal battery and that means that you cannot operate it unless it is connected to a 12 volt power source. Connecting it to your computer via USB allows you to install map updates, check for firmware updates, etc, but you will not be able to use it as a gps while it is connected to the computer. There is nothing wrong with your gps.
To use your gps in the home you need to purchase a 12 volt adapter, there are several types, plug the adapter into your wall outlet and connect your gps to it. If you can sit near a window it will help in picking up the satellite signal. Just keep in mind that you cannot connect the 12 volt power supply and use the usb cable at the same time. Enjoy your gps.

The problem lies with the fact that a standard mini usb pin-out has + voltage on pin 1 and ground on pin 5. The navigon is programmed to recognize this as a computer. The navigon charger however has + voltage on pin 4 and ground on pin 5. The reason for navigon doing this as opposed to following the standard pin-out is due to the unit requiring a stronger power supply to charge the battery. USB current output on a computer does not have the capacity to do this. As a consequence, you will have to find a charger that has the right pin-out for this device ( + on pin 4 and - on pin 5 ). The tough thing is, there is no way to tell one from the other, they look identical. However, I have found that chargers with a capacity of 1000 ma or greater are pinned-out like above ( + on pin 4 and - on pin 5 ). Other than using a multimeter to verify the pins, the only thing to do, would be to plug it in and see if it works. Hope this helps.
