    I installed an aux port on my car stereo. My phone continues to play thru the internal speaker when plugged into the aux port. I can listen to headphones perfectly fine. I plugged a adapter with dual ports into the phone and one port to the headphones and one port to my aux and it works. There seems to be some impedance requirement for it to switch. Anyone else come across this issue?

    No impedance required to switch, it is a mechanical switch when you plug in the headphones.
    Make sure the cable you are using is completely seated when you plug it into the headphone jack.

    When you say you "installed" an aux port on your stereo, do you mean you wired one in yourself or used an existing one? If you wired one in yyourself, then I would recommend checking your wiring or trying another device that uses a headset out jack to test it with.

    Perhaps I wasn't clear enough in my original post.
    I installed an aux port for my car stereo. Using other sources it works fine. My RAZR Maxx continues to play thru it's internal speaker when plugged into the port. If I use a dual output adapter with one side going to the AUX port and the other side going to a pair of headphones it outputs to the headphones and the aux port. Life is good. If I leave the setup exactly the same but do not connect the headphones the RAZR continues to play only thru the internal speaker. Not good. When I plug the headphones into the other port it switches to the headphone port. Life is good again. I have tested it several times. It performs as stated every time, meaning it's not a fluke.
    That's not a mechanical switch.

    Sounds like your connecting cord is the wrong type. Look at your headphone plug. How many black lines are there? Connection Cord lines? There could also be a difference in manufacture tolerances of the connection cord vs the headphone jack. If the headphone jack was slightly larger and connection cord is slighter smaller the Droid female connection would no longer make proper contact with the male plug. Try swapping out the Line IN cord.

    Check the shank on the jack plug when inserted, there should be about 1/32" showing. Mine had about 1/8, Pocket fuzz is blocking the insertion. Power the phone off, I used a dental pick (metal not a tooth pick, like they use for cleaning teeth) to hook under the compacted fuzz. Tap the phone to dislodge the remaining fuzz then blow it out with compressed air.

    Please just close this thread. I am either failing to convey my issue or people lack the necessary reading comprehension.

    I bought a used Ipod Touch and for my car; it works perfectly. By the way, my RAZR still works flawlessly with a pair of headphones, just not my car aux.

    I resent that statement. I think the people who have responded to your question have done so in good faith and to the est of your efforts. Every one of the suggestions above was a valid one in my opinion. I can appreciate your frustration but there is no reason to be disrespectful.

    had you not said this, i too would have said its a mechanical switch because that's very common.
    assuming you put a "line level" input on your stereo, you may want to try and put a small resistor in line to reduce the signal from your phone, which also should simulate the headphones and make the phone output through the jack (again, assuming that's whats needed to make this work).

    im by no means an expert at this and am speculating on what might work based on your situation. a quick google search should show you how to make the connections.
    if you can, pop open the speaker on you headphones and look for the resistance of the speaker ( a value of "K", like 4k) and try a resistor of that size.
