TomToms play nice with Mac OS. My original TomTom 910 had a 20GB hard drive and a battery that lasted a minimum of six hours. I traded up to a TomTom920. The 920 is based on a SD card. Without the HD, TomTom was able to use a much smaller case. Unfortunately, the battery in the 920 barely makes 1.5 hours. I also keep getting offers for map upgrades at $39.99 but, when I follow the link, that special price is not available.
