I have a SD card which goes in the car (Mazda) to provide TomTom maps on the built in sat nav, but I can't seem to update the maps. When I put the SD card into my Mac computer and try and install the software from the driver on the SD card it says the software is too old to run on my current operating Mac system. Then I've tried to download the latest software from the TomTom website but it won't recognise the SD card. The SD card says "Australia 2014 KE12 66 EZ1B Maps by TomTom" on it. Is there any way I can update the maps on this SD card or is it too out of date?
