The approach we are taking is consolidating a lot of the data that Google Analytics provides you into scores. These are found throughout the dashboard and reports, which give you a gauge to go off of for optimizing. This is opposed to exporting all of the data manually and creating your own algorithms to discover new opportunities and figure out what needs to be tweaked, which we've found people do.
The scores and the way the reports are laid out save you time because of consolidation and at a glance views. We have plans for even more powerful features that allow you to manipulate data even further which Google Analytics is not capable of too.
Do you have an idea of who your dominant customer segment will be? That'll help you determine a more pinpoint entry point for pricing. Pricing is definitely tricky to work on though.
I recommend doing some split testing of the pricing for your plan and seeing which dollar amounts convert across all your versions.
Either the manufacturers load it onto the car when its built or you can buy the standalone system itself. Apple has partnered with car manufacturers like Honda, Ford and Kia and select models will likely come with it.
Pioneer recently came out with their own standalone system with CarPlay which you could install yourself.
It would be interesting to see if they give you the options of choosing what system you want when you initially purchase your car. CarPlay vs AndroidAuto vs Other ones.
