My Trailhawk is early 2014, I have not noticed any issues with the navigation. Seems to work fine in South West WA and Perth.

51000 km on it now,only one hiccup so far with an unexplained electrical fault of "low bus voltage" which saw the vehicle lose most of the ancillaries, including cruise control, blind spot, indicators, air con, power windows etc. Volts showed as 13.6 (usually 14.0).

Roadside troubleshooting was removal of the battery leads and checking any earths I could see under the bonnet, continued trip after deciding that the alternator was charging and things having started working again albeit with a check engine light on the dash. CE light eventually went out and on returning home and into dealer for service they could find no error codes? Six months ago and it hasn't done it again?

Almost trusting it again....
