So far (since first released in May)
Having pre-ordered ours, we picked it up the first day of release locally. I have numerous vehicles and the CHR is currently sitting in the garage still Spring at just over 6000 km's. I have followed the Navigation threads with some interest but have decided ours will stay as is for the time being. I will try and get around to posting how I have mounted a Garmin GPS. I had to modify the USB plug to enable charging only otherwise the infotainment unit would try to sync all the time. I have a lift in my garage and will be doing my own maintenance.
