I have got a little further with tomtom 1.2 apk and Australia915.5074 map also tried TomTom Australia v1.2 (Map v910.4963 got them activated on the sd card then in airplane mode
tom tom starts and gives this message problem with map you cannot use this map on this device Australia 7-99 I also get the same message with this map Australia -817
any help appreciated thanks this is on an xperia z1 rooted

From my expereince you need to use the android tomtom maps or have the apk which allows multiple maps. Thats the only way I managed to get any map work.
