Apologies for the slight "forum drift" - but I bet you guys know the answers.
I drive a plethora of motor vehicles - rarely my own, often rented from Hertz or any one of numerous "company" vehicles.
I carry an XM satellite radio with me, which has a built in transmitter that allows me to hear the output through any standard car radio.
I also have a stand alone transmitter, with the standard mini jack (3.5 mil?) input. I can connect that to either my pda (for satellite navigation voice commands) or to an MP3 player for my own choice of toons.
A recent experiment to combine both the pda and the mp3 player, through a simple "2 into 1" cable, worked A BIT - but the audio quality of the mp3 was seriously degraded and, after a few minutes, the mp3 would cease to operate - but would reset and start again for a short while.
I'm told that the problem may be something to do with the impedance of the two units and that the pda "pulls down" the mp3 - which I believe but find confusing if they both work through the same cheapie headset.
Any thoughts as to how to mix the two signals - pda and mp3?
I know one answer would be to put my toons on the pda, start windows media player and then start the TomTom navigator - but that's the chicken way out.
