Bought a 2014 Mazda SE-L just the other month, and I am really enjoying it so far, very easy and fun to drive.
Regarding some of its connected services, I see stitcher is available but I cannot find the Aha app on my android device. Says it was created for an older version of Android! I guess they never updated the app in that case.

Also is it worth installing android auto / carplay or is it too risky? I don't want to mess up the system.
