How To: Build and Hardwire an Auxillary Input to OEM Stereo
#286
Thanks PureDrifter, I will recheck my rca heads. I still am a little confused about the amp. Do the wires you splice onto behind the cd changer not run to the amp and then to the head unit? Or do they run straight to the head unit from the changer and then to the amp and last the speakers?

for the nakamichi models (98-01? only) the cd changer feeds directly to the headunit, then the headunit will output sound to the amplifier which sends it to the speakers+sub.

Anybody know the wires/pinout that I have to intercept for a 97 sc300 stock pioneer system ? Also where are you supposed to draw the power from so that the dock connector will charge the ipod? Lastly can I solder a resistor to the power source to only draw out 5 volts so it can charge my iphone properly? Thanks

My iPod Touch's AC Adapter says it puts out 9.5V / 500mA. I emailed David Navone about this today because I was curious what he recommended when using his cable. David wrote back and said that "Depending on the generation, the iPod will have internal regulation for the battery... You won't need the resistor... ".

My ac adapter says 5 volts. The Iphone is pretty tricky with the voltage. I read on some iphone forums people using older ipod chargers with higher voltage and burning out their phone. Ive tried using one of my old ipod chargers one evening and the next morning it didnt even take the charge. In theory though, I can just split the power and solder a resistor to it to output 5 volts correct? I'm not much of an electronics person (circuits etc). Thanks

If you're not an electronics or car audio wiring expert, why dispute the opinion of someone who is (David Navone) ? If you have questions about using his cable with an iPhone, you should email him directly -- I am sure he will answer them for you. He has answered several of my emails whenever I had questions about this cable. I think the situations you are referring to involved earlier iPods using chargers meant for later units.
My reading seems to indicate that most 3rd party chargers supply voltage to pins 19/20 and 29/30 on the iPod connector. These are the firewire voltage charging pins, and are supposedly rated up to 35v for power input. My AC adapter I use with my iPod Touch indeed uses these same pins; the David Navone cable has a smaller clearance so I can't get my meter probe inside to check the pins.

The thing is, people who have used the firewire chargers (ie older generation ipod chargers) have been known to burn out their phone. I've researched some more on this issue and what I'm gathering is that the iphone does have a internal regulator but not a very good one. The voltage spikes in the car have been burning peoples phones. The best way to not do so is to use a car charger that has its own regulator and connects using a usb-dock connector cable. I emailed David some questions and I'll let you know what he says.
Also, one more thing. I think the touch is less of an issue because you are closer to the 12v output of the car with the requirement of 9v. The iphone on the other hand needs only 5v which maybe why so many ppl burn out their phones.

The requirement isn't necessarily 9v -- that's just what my charger puts out. Charger was $5 on eBay. Has worked fine since I got it in March. Like the iPhone, the iPod Touch can be charged using 5v on the USB cable just as well as it can be on the AC adapter (albeit each method seems to use different pins).
