Re: Garmin Nuvi 610T

You can try a master reset. With the unit off hold your finger on the upper right hand corner of the touch screen and tap the power button.  Continue holding your finger on the screen until you see a message "This operation will erase all waypoints, do you want to continue?" (this could take up to a minute)

Tap yes and the unit should reboot then attempt to acquire satellites.

Was working fine and suddenly deided to lose maps. message on screen says "no detailed maps found that support routing. The nuvi cannot be used without them." What happened and how do I GET THEM BACK. ...

Call up Garmin and have them walk you threw a trouble shooting procedure. It sounds like your unit has erased itself by no fault of yours. Garmin will replace it once you get ahold of them. There is not anything that we can do without thier support.

Voice directions not working.

First, ensure that you are using the unmuted internal speakers by pressing the power button twice while the unit is on.

Do you hear beeps (button tones) through the speakers?

These are a couple things to try:

1. Change the voice from English TTS (JILL) to English TTS (JAKE) - This will demonstrate whether the voice database has been corrupted.

2. Tap the power button twice while the unit is on to switch back to fm transmitter and attempt to use your radio to tune the sound. If you succeed here, you may indeed have a problem with your internal speaker. A return of the product may be necessary.
