(This is my second attempt at this thread. I apologize for the bad pic links. I couldnt edit my post, so I will have the original deleted. Enjoy!)
I had the problem that I know many people have. You have this mp3 player that has tons of music on it, all my playlists, and I cant even use it in my truck! I have tried fm modulators, but here in northern NJ near NYC, its hard to find frequency that is totally clear. I tried a few different modulators and was never satisfied.
When I bought my Pathfinder, I stumbled upon this board, and found a thread about the Pac AAI-NIS Auxiliary Input (thanks aaxeman).
Its a complete plug and play adapter for late model Nissans with optional Sat radio. Basically what it does is hacks into the input for the stock sat radio and allows you to input through rca cables. You even have two inputs. I plan to use the second for a dvd player down the road.
Its as easy as pushing your radio button till Sat-1 comes up. Only thing I needed was a cable that adapts a headphone jack to two male rca jacks(few dollars at radio shack or other electronics store).
I received the unit and then had to figure out how to get that damn radio out. I downloaded the Factory service manual, but their directions aren't too clear. So I will go through it step by step with pics below for everyone else's benefit.
1. first I removed the tray in the middle of the dash. It just pops up with a little force. I didn't use anything to pry, just my fingers. When you get it off it will look like this. Next remove the screw behind the tray.
2. Then move down to the the cupholders. Pop off the trim around them.
3. turn the ignition on and put the shifter into 2nd. Make sure your emergency brake is on. Take your key back out. Then from the bottom pull up on the trim around the shifter. Work your way around the edges to pull the whole piece off.
4. starting from the top of the dash, now remove the final piece. There are several wiring connections for the temp control and ect. You can disconnect them, or just move the panel to the side intact(what I did).
5. Now remove the 4 screws that hold the receiver in place. The pic shows 2, there are two more on the other side.
6. Now disconnect the 10 pin main plug, and the 12 pin sat plug. They are the two that are empty in the pic below(there was one empty jack on mine, disregard it). The pac unit "jumps" in between the main plug. It basically taps into the power wire on the main harness. The plug that was in the sat jack you don't need. Just tuck it away. Then plug in the one from the pac. don't worry about plugging in the wrong one. They will only fit in the right jacks.
Thats it Basically, just do the reverse to put it back together. Its much easier then it sounds. I was just trying to me thorough.
The only other issue to think about is where to have your plug come out. I used the "cubby" hole in the middle of the dash. I drilled a small hole in the back corner, and fed the wire through there. This way I can push the cable back in to just a few inches of length, or pull it out 2 feet or so.
Any questions or comments are welcome. Please let me know of any errors and i will correct.
