I use my Axim to listen to audio books in the car on long trips which I take regularly. My car cd player has an 1/8 inch input so I can plug my Axim directly into the stereo. It works fairly well except the volume is a little low. But some times the battery will get pretty low on long trips. So what's my solution? Just plug the Axim into my cigarette lighter power inverter. This plan is great up until I turn the stereo on. Then I get a terrible buzz which clearly overpowers the audio coming out of the Axim.

This is obviously the result of poor grounding. The only solution to this I have discovered is to listen to my audio through a headset while it's charging. This is obviously a less than adequate solution. I imagine that I am not the first person to encounter such problems. Does any one have any ideas about how to solve this obnoxious problem?
