The preferred* navcore for the GO510 is 7.903.
This navcore (I think I'm correct in saying) can address only a 2GB SD card (not an SD HC card), and is quite limited wrt compatible maps, which is why I tried the Europe East 905.4757 on this device. Wheras I had originally found the problem with Europe 905.4757, this is too large to fit on a 2GB card.
My "virtual drives" in Cyprus for
both maps were identical on my smartphone and the "virtual drive" on my daughter's GO150 with the Europe East map only,
exactly the same: this is what was filmed for the Youtube clip.
My daughter has now gone home (about 230 miles away) and I don't have access to her Tomtom to try any other Navcores.
What navcore would you now recommend? - I tried 9.051.503855.2 on her GO510 about three years ago (I think this was then recommended), but found it to be unstable - loosing sound & tending to switch itself off, so reverted to the official version.
