I'm sorry about the issue. Do you see any other model on the Garmin Nuvi GPS device, such as 2507, or 58LM, or 140T, etc.? How old is it?
Do you have any Garmin program installed on the computer?
What happens when you click on buttons for download?
When you plug in the GPS device to the computer, does the computer make any sound?
Do you have windows xp, vista, or 7, or 8, 10, or mac computer?
Can we do a remote support session, so I can troubleshoot the issue directly on your computer together with you?
Please reply at the box below. Thank you,
