Well spotted Aitese!!
I hadn't bothered downloading the update to maps as I was using Brut maps and it worked well enough for me. However downloaded the update today, selected that newer version of maps for navigation and it is working. Haven't compared it against the cracked version (sat in an office) but looks to have more information on the screen etc.
