How do i turn the volume up on a tomtom 900 - Tomtom GO 910 GPS Receiver

One the main map view, touch the bottom, left of the screen (Where your current speed is indicated). You should then be presented with a volume slider at the bottom of the display to adjust the volume with.

You can change the volume of the spoken instructions by using 'Volume preferences' , with its sliding scale to set the required volume in increments of 5%. The 'Test' function is a good way to get the volume right before starting your journey.
You may also find it helpful to use 'Link volume to speed', so that the spoken instructions get louder as road noise increases and are at their quietest when you are stationary.

To rase the volume you need to press the Change preferences. Then once there tap show all. Then you look for the Volume preferences to turn up the volume.

You can get the manual on link below and on page 32 to 34 it will tell you how to change.

What model do you have? Does it work sometimes and not others for turn by turn directions? If you have a XL 350 TM there was a problem with the version updates. Here is a link to the TomTomHome website that you can access. http://us.support.tomtom.com/app/answers/detail/a_id/12510/kw/tomtom%20volume/sno/1

Hi,

You should be able to adjust the volume usind this method.

With the unit turned on and displaying the map, tap the bottom left side of the screen.

A sliding bar will appear at the bottom of the screen. You can now adjust the volume to your desired level.

The volume menu is also available by tapping and entering 'Preferences menu'. You can also set the volume from here if you wish.

Users will continually need to quickly change the volume on a TOMTOM units, depending on the loudness of traffic noise, the radio or conversations. Although there are no external volume controls, the volume on the ONE can be easily accessed on screen by touching the bottom left corner of the map display. Once the volume controller appears you just slide your finger to increase or decrease volume. We found the audio levels a little softer on this unit and had to set the volume to around 60% or 70% in order to clearly hear it.

Please rate my help++++Thanks for using Fixya

tap the bottom left hand side of the screen and the volume bar should show. then use your finger to slide the volume up.

Maybe you accidently turn OFF or reduced the sound volume. Tap the screen to go to MAIN MENU, then tap the CHANGE PREFERENCES, you might find a speaker's icon with words TURN ON SOUND. Tap it. If still not working, check Volume Preferences to set the volume level of sound.
Hope it might help

Click on OPERATE MY ONE XL.
Click on CHANGE PREFERENCES
Make sure TURN OFF SOUND not clicked
Go to next page.
Click VOLUME PREFERENCES.
Move slide to preference and click TEST.

My problem is that after driving for a while the volume reduces to where it can't be heard. Anyone else have this problem.
