I've got the TomTom XL Live IQ Routes Europe v9.058.568435.2 running the original map Western_and_Central_Europe_2GB v845.2645 and want to update the map to v870. Unfortunately they have increased the size of these maps beyond the 2Gb of the devices memory and introduced 'map zones'. I've downloaded Western_Europe and Europe_West versions 870.3406 which I assumed would be equivalent and suitable for this device. However, after patching and installing them, the device states that they cannot be used.
I've successfully downloaded, patched and installed a map on my HTC mobile, so I think I know what I should be doing.
Has anyone got any idea which Europe v870 map would be suitable for the TomTom XL Live IQ Routes?
