@pe1agp I have had a chance again to play with my mate's TomTom Toyota II. Sadly enough, the 9.510 navcore did not work at all. I patched the original 7.828 navcore and be able to use the latest map but as this navcore does not support any of the advanced features (e.g. ALG), I am still looking for a way to get a 9.x navcore running on it.

Navcore for TomTom Toyota II

I still have a strong feeling that some special driver is needed for a newer navcore to work on this Toyota unit. The 128MB memory must be there for a reason. Where can I find a tutorial how to make a custom 9.x navcore from a working 7.828 one?
vda767 Reviewed by vda767 on . Navcore for TomTom Toyota II Hi, A friend of mine has a TomTom Toyota II sat nav, 128MB RAM, running unpatched navcore 7.828. I tried all navcore in Downunders' Automatic Navcore Installer but none of them worked. Does any one know or have a patched navcore for TomTom Toyota II? Any help would be very much appreciated. Thanks. Rating: 5
