Re: is it possible to get tomtom truck to work on an old go700
It is possible and it works very well.
You have 2 choices though,
1, Use older maps, I managed to fit 865 maps and 8.398 navcore on a friends 700 with a bit of fettling,
2, TomTom GO700 Internal Drive Change follow this guide and change the drive for a bigger one.
I have used Navcore 8.398 and the 885 truck maps on my Go 500 needs a 4gb card though.
