Ooh a CoPilot user!
I dont suppose you've used TomTom per chance and compared the two? CoPilot looks very lush actually!
I've just put on TomTom on my Stellar, works a treat! But if I can just get it to display in landscape mode without having to open my keyboard...
I've not used TomTom on the phone but used to have a TomTom One. So far I'd say its as good as that. When I switch on CoPilot in the car I get a GPS lock almost instantly. Have a look at the review here.
