S14DST, sorry it didn't work out. If you provide more info about your car and what radio you have, whether it's a Pioneer or Nak system, would really help out.

I really need to compile all the years that this mod works on....i'll get to that shortly.

I'm sorry to tell you guys that i don't have any clue when it comes to the Nak system. I'm hoping someone can post detailed pictures of the insides of the head unit. I know soon i'll be working on a 99 Pioneer system and will be checking to see if this mod works with the 99-00 radios. Anyone in VA have a spare Nak head unit that they're willing to let me see? Lol.

My Griffin DC plug-in iPhone charger is giving up the ghost. Since I already have an Escort radar scanner taking up the only outlet on the dash I've decided to get that Pyle Audio iPhone charger to replace the Radio Shack ground loop isolator, since the Pyle has the same function built in.

http://www.pyleaudio.com/sku/PLDN36I...io-Line-Driver

http://www.amazon.com/New-PYLE-PLDN3...=1FCX8331JJLWD

It's plug and play just the same as described earlier in this thread with the exception of hardwiring positive and negative connections from the DC port.

I took apart my Nakamichi system and the circuit layout is all different, so I took a guess and failed. Any help would be appreciated!

I guessed the white connector at the bottom left could be where I solder my AUX to. The connector has 4 pins, and the middle two are ground, so I assumed the other two are the left and right. The assumed left and right pins are connected directly to the tape sensor, but I'm not sure if it's the appropriate place to solder the AUX onto.

I didn't know which is right/left, so I just soldered it on and tried it, but it sounds like garbage. If I got the right/left soldered on backwards, it should still have sounded good, right? (Like putting on earphones backwards)

I installed the Pyle PLDN36I groun loop isolator tonight. It seems like it COULD be good (especially for the price of $23 from Amazon)... but here is what I didn't like:

1) volume has to be WAY down low to use the CD button passthrough and not overload or blow out one's ears.

Is there such a thing as an inline device that reduces the audio load to "line level"? That would solve this issue.

2) the ground loop isolator didn't act like a ground loop isolator at first. Tomorrow I'll see if it does this again when I turn over the ignition

3) It won't charge my iPhone 4. I am going to recheck my connections again tomorrow but the phone recognized it as a "Dock Connector". All audio functions are fine. It just won't charge for some reason.

I also plugged in my pre-dock-connector iPod Nano gen1 to see if Pyle had just made an antiquated design. That didn't charge either so I am assuming it is either something pulled in my wiring... or the problem is with the Pyle itself.

I had hoped this would be a final solution to the mess of DC power cords I have hanging off my console. More tomorrow.

I've given up on the Pyle. Their customer support is also unavailable due to their being on EST time. I'm over it. I'm tearing it out and going back to the radio shack setup-- which worked perfectly.

UPDATE: I went back to the original setup and have returned the Pyle unit. I made one addition. I used a Serpac (www.serpac.com) model #321,BK electronics casing, threw away the bottom half and fit this into the armrest console with a radio shack stereo connector which I drilled a hole for. I haven't mounted it permanently yet but it fits perfectly and looks like it could have been as OEM as my factory Lexus Phone system. There are four posts on the casing that you can take a small drill bit to so that larger and longer screws can be made to fit for permanent mounting in the console floor.

This gives the blank hole in the console (where the Lexus Phone used to be) a clean bezel cover and aux port. Wiring/soldering is as easy as getting a short stereo 1/8" cable, cutting it off with some slack and stripping the wires to be soldered onto the connectors, which you can test for L/R channel.

Simple and clean. I will snap a picture and post later if I can get through some other things tonight.

I know this is an SC thread but i took out my '00 GS3 head unit and disassembled it down to the tape deck and found two leads labeled R and L. Im just going to throw this up and see of anyone bites but id really rather solder an RCA cable to the tape deck than cut a bunch of CD wires...Click the image to open in full size.

Default It WORKED!

This worked like a charm for me! Thanks to pieisgude and Ali for figuring this out. saved me $200 for doing this at bestbuy. As for the interfering input issue, the easiest way i found was to plug in a headphone jack into the mic line on the computer an record something. The PC things its got a mic connected but records complete silence, the i burned the same track 15 times on a disk and put it into the cd changer, now i just have the CD 12 run on infinite loop while i have my phone hooked up. Hope this remotely helps someone and thanks again.

Cant you just put a cd in the changer upside down and make the headunit error out?

In case anyone is still experimenting with this mod, I was searching around and found this link on the net http://www.jalopyjournal.com/forum/s...d.php?t=300222. I may not be able to post links, or have broken a rule by posting, I apologize if I have done such. If I have violated a rule, someone with the authority, send me a PM and I will send you the link, review and post if you find it valid. I figure this is how, the person mentioned above that charges to put the Aux port in is doing it.

Awesome!
BlaXXXima I know you paid for your mod to be completed, but it would really help, if you still have your radio to post pics of the internal components, that shows how it was done. We could use the pictures to trace the wires from the AUX port back to it's source on the system board to see where the connections are made. This would really help us modders to figure out how to do the MOD on the NAK system.

In my SC the tape deck is broken but requires a tape to be in it to keep some other functions working. My CD changer is also broken and won't read CD's but still displays "CD Err" any time I switch to it as long as my changer caddy is loaded or if the loading bay is tricked into thinking it has a cd caddy loaded.
