Power to the Motherboard problem or just Battery needs changing
How can you tell if the mother board needs replacing or just the battery?
Released July 2007. It is a gray two-tone, 7.5 x 12 x 2 cm device, with a 4.3" screen, that is identified by the word: nüvi.
georgeelias1950 measuring a battery with a multimeter will only show you the voltage of the battery but it will not show the condition off the battery. Even a battery that shows the proper voltage may have failed if it does not supply the amperage required by the device. To determine that, you will have to put a load on the battery and measure the amperage. Not an easy task on the type of the battery for your GPS. I suggest that you start by replacing the battery regardless of what voltage it shows. If nothing else, it will provide you with a known-good point if further troubleshooting should be necessary
