On board Navigation went on the blink, couldn't get it to find any locations even Go Home, nearly did a factory reset but then I found a post by Steve_M 1. forcestop the navigation app - General settings> System> Detail Information> App Manager then find navigation in the list and select it and select the forcestop button. go back to Home screen and reopen the Navigation app. This did the trick, now working correctly. This got me thinking, is there anyway to backup my favourites etc, they have that on the Yaris. There is no way to upload a custom route, this is avaliable on Honda motorbikes with Garmin, why not on Honda cars. No traffic info and red light speed camera warnings which I had on my standalone garmin in my last car plus route upload and backup. Why have we got a lower spec navigation on the Jazz? Might use Google Maps but that doesn't always fireup when using wireless android auto, it's a pain having to plug the phone in everytime.
