I recently went to Car Toys to play with the F90bt before the 2.0 update, and when I hooked it up...NOTHING came up on the Head Unit. I was able to play music through the HU using the controls on my Ipod Touch. I read that the 2.0 update has "improved compatibility with the Ipod Touch." My question is...What are ALL the things it could do now that it couldnt do before?
