Is there anywhere in the menu’s where we are able to see all the tunes we have created and saved/shared? I’m getting tons of cash for downloads, likes, and uses, but having trouble find out out which tunes are being used. A single area to see all tunes you have saved would be AWESOME!!!
Unfortunately you have to sit in the car and check tune by tune this way… 
You can see all the layer groups and all the car paints in one place.
Sadly with tunes you must go to MY CARS jump into a given car and then go to my tunes and see what has been downloaded. Then you must repeat this for every car you have tuned.
I like to keep a file with all the cars I have tuned and what the build/tune is just in case anything happens. It also lets me stay organized - you could use something similar but record your download stats there as well, make your own trending data.
