Salam In what format does the toyota Sat Nav system read the GPS SD card? I have a genuine Toyota SD card but it has middle eastern maps, and I need australian maps. I have downloaded the Australian maps but it is in ISO. file format, and when I transfered it to an SD card and played it on my toyota sat nav system in the car, it didnt work (the sat nav system does not support DVD format). What do I do? Bit lost. What format does the toyota sat nav need to play and can I convert the ISO file? Anyone good at IT and knows what file formats are needed to work on the toyota gps system? The system that runs it i think is WhereIS. Any Help would be appreciated as I am very confused. Thanks in Advanced
