Troubleshoot using Driving Guidance

This topic contains information about how to troubleshoot problems that can occur when you use Driving Guidance with MapPoint.

The Driving Guidance feature is not supported on computers with screen resolutions less than 1024 by 768 pixels. If you start Driving Guidance with a screen resolution setting below the supported levels, the controls do not display correctly.


To get the best audio output from Driving Guidance, check the Master Volume (or Volume Control, depending on your audio hardware and software) and Wave settings on your computer.

To change the volume settings

  1. On your computer, in the Control Panel, open Sounds and Audio Devices.
  2. Click the Audio tab.
  3. Click Volume in the Sound playback section.
  4. Move the Master Volume (or Volume Control) and Wave sliders to the top for maximum volume.

  1. Double-click the Volume icon in the notification area.
  2. Move the Master Volume (or Volume Control) and Wave sliders to the top for maximum volume.

First check to see that your computer is running Windows® XP operating system.

Next, check the following possible text-to-speech problems:

The speaker volume is not turned up or is muted. Some speakers have external controls for volume and muting. Make sure the volume is turned up sufficiently or that muting is off.

The speakers may not be selected as the current output device. On the Text-to-Speech tab, click Audio Output to make sure that the speakers are selected.

The speakers might not be connected properly. Consult the speaker hardware documentation for additional information. Make certain that the sound card for the computer is also properly seated, installed and that the correct drivers are available.

The text-to-speech engine may be corrupted. To test for corruption, switch to another engine. If another engine is working properly, reinstall the specific engine from the original source. If no engine is working properly, reinstall the SAPI component from the original source or CD.

If Windows Media® Player 10 series is running, try turning it off.
