I am liking menu_2! I think I would leave menu_1 with "tuner" or "radio" that way its not so specific and you could use it with XM, Sirrus, HD, which ever radio you use.
Also to get the button 'press' effect you need to go into the DOT effects and change the bevel effect from UP to DOWN on the menu_down.jpg
Looking good fella's, i think the SDK file is more popular than the skin archive
