Installing TomTom on Binatone G500

Hi,

I`m trying to install TomTom on Binatone G500. I have TomTom 3rd Edition working on 2 other TomToms one a A430 an the other a B430. It works/loads perfect on these TomToms but this G500 will not bootup in to TomTom, It just loads up the Binatone software. I`ve tried to copy everything I have off my other working TomToms onto a new 2GB MicroSD card but it will not work. The same card runs OK on the other TomToms.

Any help anyone.

Thanks
