Hi Guys, Ive lost the SD card for my TOMTOM one. Could someone please explain i can reinstall the maps. I have another blank SD card.
I have had a look at the site but do not understand what i need to do. Please help.

You can't have been looking too good as otherwise you would have found tutorials like this for example.
Get a suitable Navcore, add a map and activate with FastActivate - which might require to boot the TT first so a ttgo.bif file is created.
To avoid furthe complications I suggest some reading in the tutorials to get used to the terms and procedures - it is all very simple!

thanks

To add a bit to Downunder's post, a new ttgo.bif file is created everytime you boot your unit. After you put a navcore & map on your card, patch the navcore and attempt to boot the device to create a ttgo.bif. If you have a problem with this, let us know.
