Froyo Samsung Car Cradle Patch
If you’re a car driver and you own a Samsung Fascinate running FroYo, XDA forum member adrynalyne has made a minor modification for the music player and presented the community with a car cradle patch.
The XDA dev states that not only does this have all the functions working, but that the music player also works with the stock AOSP music player or music mod.
You’ll need to flash via ClockworkMod.
