GO Mobile app v. TT standalone
Although I hate to say it, I'm seriously thinking about getting one as the app is just so bad and the pace of change is SO slow. I use Satnav for work everyday and I just cant have it not work well. Traffic and speed cameras an absolute essential.
I've tried every iOS app going and they ALL have problems - the only (pretty much) perfect one was the old TT app, of course, which makes this whole problem even more annoying.
