I somehow disabled my fm transmitter when playing with it trying to change the frequency it was tuned into, and I cannot enable it again. I have tried everything. Any ideas on how to turn the fm transmitter back on? I checked the manual and did what they say, but every time I press the dog(select) button after going into the "fm disabled" menu option, but it just goes back to the current song. Anybody who has had this problem if you could help. Thank you!
