Hmmmm, Yes I have sometimes noticed it does switch itself back on but that is still a bit crappy simply because as soon as it goes off the radio plays static.

Driving down the road listening to static is a sure fire way to make oneself crazy!

Also when it switches itself back on the power level is now 113 and not 118 so it is still very staticy

You know sometimes the manufacturer just trys to make things too clever. I turned the FM transmitter on and I expect it on, not sometimes on!
