I bought a 510 Traffic edition a couple of days ago, have not really had time to try it out yet but i got a good strong signal lying in bed setting it up and reading the manual, the new mounting shoe looks a bit weird and flimsy, TT have already had a recall on 'drooping' mounts, so i need to see if mine is on the recall list, there are speed cameras/speed limits pre-installed in the under the TT plus section, but i suspect when subscribe via the TT website you will have to pay for the updates.
