Connecting Qtek 2020i to the car audio
I bought a car audio Panasonic DEH-50UB, an audio player that has an AUX connector for external source and want to use it together with my Qtek 2020i. I connect the car audio and PPC through the audio connector for headphones.
The problem is that I can not connect Qtek 2020i both to car audio and power supply via cigarette lighter.
When both cables are connected, I hear noise coming from my car loudspeakers. This noise appears while no audio signal is transmitted. During the playback there is no noise, but it reappears in the pauses between audio files. After 5-30 minutes of playing back the music my PPC hangs.
This situation is very disappointing for me, as I was going to use car loudspeakers for navigation to receive voice instructions form iGO etc.
I made some tests, and here are the results.
The PPC running on its own battery transmits audio to car speakers without any noise. That would have satisfied me, but this way the battery drains out.
If a PPC is connected to the power supply from the lighter, its own speaker produces no noise. Still the sound is too quiet.
The PPC works well with computer speakers both when it is connected to external power and whet it works with its own battery.
The USB adapter for car lighter works the same as the ordinary power adapter.
Does anyone know the solution for my problem?
