Query: Not too happy but can work.

I needed a transmitter that also charged my iPod so I bought this unit. The display is difficult to read on sunny days. I live in a very populous area where every other station is in use. Unused stations have alot of static and has sound bleeding through from the station before it. Transmitter is too weak to broadcast through without static. You cannot preset buttons so it is impossible to change stations while driving. Still, I can set it to 87.9, which is pretty clear in my immediate area.
