Memory card on the TomTom 720


Can anyone tell me what I can do if I add a memory card to my TomTom 720? I tried loading audio books to it but could not get them to work. If I am using the map thats in memory what can I do with a memory card? My instructions don't say much about how I can use one. Thanks

Not real familiar with T2's but my father has one and it doesn't seem that you can use it with the SD card out of the slot, hence, it is really only used for maps... I could be horribly wrong though.
