Hey guys, just got my new HTC hero. Everything's fine, been installing apps like crazy, sorted out videos, but not for the satnav.. For some reason, when I go on Google Maps, it minimises right out of it to the home screen where my clock is. If I hold the house button, it's still open, and if I go back to it again, it will just minimise again after a short while. I got it to stay open once, but now it's just messed up Any fixes or alternative Sat Navs I can use? Thanks.
