Next simple question, what do you want to use your TomTom for?Should it be a truck version or for normal use?
What I can offer you is making a working SDHC card with any map you like here on my GO 950 with my own ttgo.bif file.
If that works here and you send me your ttgo.bif file then I can provide the working card here with the just patch and put it all on my own server and send you a private link to get it.
Interested send me a PM, please.
