Guess I need to speak with someone more technically savvy than I am. I have an iPhone and loaded iTunes on a computer once and it took over everything to the point that I couldn't find anything. Deleted it and never let my phone touch my computer any more. Navigation on my 2017 is decent most of the time but still has new data missing. Still a bit afraid of using car play in my car.
As easy as meeting up with my Wife and I and we can easily give you an over-view.
All you need is your phone and a USB wire long enough to connect inside your console box
between the seats (discovered it working best there).
She had CarPlay in her C7 well before I warmed up to it.
Then I noticed the Infotainment map compromises too and had to consider
the fact that she was never complaining about her map as much
as I was. So I invested the time to learn Car Play.
It works best when your phone is plugged in via USB (not wireless to the Corvette).
True, CarPlay is not perfect but I am at least not paying over $150 to get
the latest map information for Infotainment that is already a year obsolete
once installed.
As well ... I am pretty sure that Google maps gives me traffic info ...
which Onstar wants $15 per month for.
Also, I've seen the NavTool that
@turbozig setup for his 2015 and
it looks like a sweet upgrade too. I know this 2014&15 upgrade would be much less
than adding Carbon Fibre to the Corvette.
