FM Transmitter help

[polo_kiwi]

Work is coming up soon, and it's a 1 hour drive away, without music..I'll probably die. /s

So I went and bought a Belkin FM-transmitter Tunecast for my car's 2004 casette stereo..
My car is a Daewoo Tacuma 2.0 CDX. purrs like a sports car..
The transmitter works fine when I'm stationary, but when I start the car and start to move it just goes to hell and white noise start to cover almost everything..

Sounds like the alternator noise is being picked up by the transmitter via the power lead. You may be able to reduce this significantly by putting a choke on the input power line.

Take a look at this site I found.
