Tom Tom external antenna - compatibility

Just bought the Tom Tom 300 and find that my windscreen blocks the signal. There seem to be a few Tom Tom Go external antennae available but no-one knows if they are compatible with the new 300/500/700 models.

Any help would be greatly appreciated
cheers

Welcome to our forums.
They should work with the whole range, see http://www.tomtom.com/products/acces...nguage=1&Tab=0 .

Unfortunately, the old mount will not fit the new Go 300. This is because the new Go 300 has a different type of connector that goes for the base of the old antenna also

Neither will the antenna....just checked them and they don't fit so there will be new ones coming out I guess.
