Not bad - works for me

Built-in SatNav wasnt an option on EX model but this app with iPhone 5S works ok. Isnt as pretty to look at as Garmin but it certainly got me where I needed to go. Does drain phone battery quickly and uses air time but I dont need nav on a daily basis so for occasional use, I am satisfied. Google maps doesnt work through HDMI interface when vehicle is moving so the only way to use the phone is to prop it on dash (not recommended) or buy holder.
