Often the ni-Cad or LiFe cells get so flat they need a special charger with high current. They just will NOT charge up any other method, it may be best if you replace the battery, you need to open up the unit to do that. There is a "Pack" inside. You can get batteries fro,m manufacturer or eBay Craig's list Google etc. However now you would also have to reinstall the software again if not lucky. There are tutorial how to do what you want on the Navman web site

Could be a number of reasons. If its frozen press in the reset button as it should be on the back.
The battery could be exhausted so try and charge it using the car lead.
The Navigation unit could be at fault or could have a dry connection at the battery or power switch.

Is this my 600 LMT Navman already charged in build or have to charge from computer?


Best to charge unit from Mains or Computer USB, then you know it's fully charged. Navman has charge in battery but you need to fully charge it yourself , then you know where you are.

You may have to go to the menu and turn on the your location option. If it wont find your house it might be because you are on a private road or the manufactures didn't update their info

Navman 40i appears to charge up but will not


if the unit is more than 2 years old the chances are the battery is defective/worn out, you say battery appears to charge up, so think you are unsure of the battery condition.

Navman won!t charge from in car charger or mains adapter but will charge from garmin in car charger


Your Navman will not run in car unless the output on the charger is 1000ma or 1a. you need to buy a genuine charger, motorola phone chargers do not have the output to run the unit

Navman N40i Not charging in car


Does the car charger cord plug into the cradle? or just straight into the unit (despite resting on the cradle) ? Do you know if anything else charges via the car charger?

Can NavMan 520 charge via USB?


that is probably due to the battery being totaly dead,
try using a mobile phone charger (nokia),
usb is for data transfers.
