When I plug the gps into the charger a computer picture shows up and I can't get it on any other screen. What's the matter?
Did you recently purchase that charger?
This usually happens when the charger is not compatible with the unit. or you could be using a non-Garmin charger. There are some "store-brand" chargers that work well, and some do not. Store brand Charger are made to be Universal. To fit multiple devices and maximize profits. You want a Garmin Specific Charger, and here is the logic why...
The reason behind it:
1. The Garmin USB Cable that you connect to your computer has a special 4-pin configuration telling the GPS that is is connected to a computer. This is the configuration most "generic" chargers use to maximize device compatibility.
2. The Garmin Car Charger has a different pin configuration with 2 less pins, giving it only positive ( + ) and Negative ( - ) to charge the GPS.
When the GPS receives the 4 pin, which is also found in a "Motorola" Cell phone charger, it will automatically sense that it is connected to a computer.
Long winded, but I wanted to explain why. Simple fix, Just go get a new charger and make sure it's Garmin compatible.
