hi, the way i got tom tom working on the rac 200 was a pain but i formated the sd card with my card reader then put the card back into the satnav and turned on the sat nav then windows mobile device centre opend up then i clicked on file managment and there is a link for brouse the contents of your device open that and select SDMMC that is yr sd card now while that is opend find the tom tom files and open mobilenavigator and change the named file from mobilenavigator to R66navigate7 once that is done just drag and drop all the files in the mobilenavigate to the sd card this do's take a while plus it might say this file might not work with yr device ignore that and add all files and once that is done u can check to see if it works and if it do's u can add the map folder as one, drag and drop again. then follow the instructions in the keygen folder and follow the steps and hopefully yr done. i had to buy a external arial to get my gps working but you can get these from ebay if yrs plays up like mine the arial you need is a
gps antenna 1m length mmcx with a 180 degree straight connector
