As far as I can tell, there are three satnav apps right now for Android owners:
They're all around the £20-30 mark (rather cheaper than TomTom for iPhone), so pretty comparable
What have people tried/used? Any thoughts? I bought CoPilot, which is okay, but uses its own keyboard rather than the Android one (which makes typing postcodes a chore), and was pretty unstable last time I used it (note: I've run an update since then, dunno if it's better now)
