GPS not working with something plugged in headphone jack aux jack

Ok I have an iPhone 3GS and a car kit from Belkin that uses the aux jack in my car, if I plug the cable in the GPS stops working. I tried different cables different car and tried my wife and daughters iPhones all with the same result. I have G-Maps, Motion X, AT&T Nav, same outcome all 3 apps.

iPhone 3GS, iPhone OS 3.1.2

weird, cause I use it daily for GPS, for the sound. it is a sound ouput, don't how it is possible to interfer with the GPS. In my car I have to specifically choose the audio source for the car kit (from within the kit). What do you mean exactly it stops working?

what happens if you plug in a headset? Myabe try in different car!

I plug my iPhone into the aux outlet on my car radio and the GPS works fine.

I have 3gs and I use it in the aux together with copilot. I'll test it with motionx and maps.

Just tested it with Motionx and I get 8 bars signal within 40 seconds and same works with maps and Google Earth. Could be interference, or hardware issue. I have a no name, no brand car kit (Chinese kit from Ebay 5 years old). I use e Belkin cable that say it works with Iphone and I also tried with an Ipod aux cable.
