Ultranew here. I have an old TomTomOne Xl with Navcore 7.13 and Maps - Australia 705.1485.
GPS is version 1.21.
Can you please advise most suitable navcore and maps I can update with
Thanks in anticipation
8.562 SE Navcore
Australia maps 845 or 850 depending on availability. Check the maps subforum for a comparative chart of Navcores and their sizes. If you have an SD card slot, your options are near unlimited. If you don't, you are limited to a map that fits the internal memory. The 8.562 Navcore works with IQroutes, ALG, TTS, the works.
Because they are very heavy for a ONE XL. The 8.562 will run smoothly on this device, but this is a personal experience of course. Some say that 9.101 also runs fine, but I have not tested that NC yet. If speed and smooth operation is not a must for you, than 9.026, 9.051 and 9.053 could be sufficient too.
