So I spent a couple of hours hacking and cracking various things to give my TomTom Go 520 not only the latest operating system from the new Go 930 but also the latest v8 UK & Ireland map to get all the cool new stuff like lane guidance on motorways like shown in the screenshot above, and this also works on normal road junctions that have filter lanes, but also voice recognition works again which has been broken for some time now on the official 7.x firmware.

As well as improved MapShare which allows you to change the map yourself to alter roads and speed limits and the like another thing you get now is smarter route planning based off all the data TomTom has been collecting for the last couple of years about peoples journeys so you are automatically taken on routes that avoid congestion at the times of day they are slow moving.

All good stuff and of course free ^_^
