This version still does not allow to use the MapShare technology that was the reason for me to follow the information from TomTom adds and buy new maps! All Mac users should refrain from buying any TomTom product. I am investigating legal action against TomTom because the only answer I got from TomTom support after describing the problem with 1.5 and now also 1.6 was "go get a PC"!
This version was already available to TomTom users that got the software with new TomTom XL hardware or alike. Although this hardware is advertised with the MapShare technology, you CAN NOT use it with a Mac because of the limitations of this "new" software.
