Google the garmin service center nearby and they will do whatever you want. Dont forget to update the firmware as well.

My probleme:

When you want to select (established) a route (Finding Location or Planing a Trip) the device machine can not calculate route and displays the following message: "Route waypoint memory is full". The device is Garmin 3760T.

I found the solution:

1. Start the device.

2. Touch "Wiew Map or Map"

3. Touch on bottom right of screen (Speed)

4. Hold your finger on top center of screen for 5-10 seconds (the speed semicircle between Trip A and Trip B). The unit would go into "Diagnostic Page".

5. Select "Clear all user data" and confirm.

Warning: will erase all user-selected data (Home, Recently Found, Favorites, Trip Planner, ....).

get a Garmin Id and sync it to that account

update the device software and see if that works if not then contact garmin and they should send a replacement traffic antenna if its within its warranty period

Hello,Does the GPS work outside of the vehicle?Where is the GPS mounted?If the GPS is under the dash, mounting it up on top of the dash will help.If the Vauxhall has a windshield with a reflective metallic coating or treatment in the glass, this may result in poor GPS satellite reception.
