No, I wish I was! I'm using NavMan at the moment, it's a bit rubbish so I'm thinking of changing to TT3 soon. I've got a bluetooth GPS unit, so I went for the cradle that looked the neatest and kept the iPaq well held.
NavMan does the job, but there are very few extras behind the program, for example you can only go from A to B and not onto C, that needs a seperate trip planning. What's TT3 like???
I had wired the headphone jack upto one of the inputs on the headunit, but it's loud enough on it's own as long as the music isn't too loud
