Sorry to hijack the thread, but I got the TT 2 Live with my 500 and have updated it previously with an updated Map and speed camera patch but after seeing this thought I'd go check to see if there was an update for mine too.
There is, but its 76mb, and there is a 2mb Speed Cam update as well, however I've only got 26mb free on the device and there is no mem-card slot or anything on it, so I'm kinda stuck with a device I can't currently update.
Does anyone have any experience with these things in regards to how to adjust the installed map pack so its a smaller variant? I don't need all of Europe tbh, just the UK.
