How to change miles to kilometres on sat. nav

Setting is on your Sat Nav, Check " Setting Section "

check your manual or ask a friend how to access the menus to change from metric to US

go to settings in message center

Go to Settings, and under "Units and Time" you should be able to change that...

if the unit was in uses while the sd was pulled out it could of damaged the files on the sd card. you can check the files on a pc but not run the files. the sd card has all the info for the sat nav system if it can not find or use a file it will not let you change the file. you need to do a scan on the sd card. its like a pc if you not eject the sd before removing it damages the filing system.also the web page is not accessible in my area. i would need the model number of the unit. there are software patches and map updates for all nav systems you may need to update the sd mapping software. from the manufactures web site

switches on but no navigation. Press navigation and it bleeps only but will not change mode for search

You have to go into the change preferences and change the speed manually, if you get stuck look in your user guide, or connect your sat-nav to your computer and open tomtom home click help click view manual
