I have a Q40 NONAV 2015 and I'm looking to get 2.5mm input from my phone etc but I can't figure out what L and R are + and -. Looking for a pinout out 2591a 1ma5e or 28051-EH00B

* XM model : 28051-EH00B
* HEAD UNIT: 2591a 1ma5e
* I managed to find the XM cable
* I am looking to take the +/- L and +-R and Ground so I can plug in 3.5 mm to my phone
* I blew 3 10a fuse plugging in the wrong cables

As for alternative methods of audio:
* NO I'm not using a Apple device ..
* NO I'm not going BT because its crap audio ..
* NO I'm not using MONO or anything like that (discord) because that's even worse then BT...
* NO I'm not using a FM Transmitter because that's just stupid its a 2015 car it should have AUX input ..

Here is what I know ...

* I have 2 Ground (the two black next to each other)
* I have Left and Right figured out but I can't tell what side is + or -
* Black / White are Right
* Red / Green are Left
* I think I just wire Left+ to TIP and Right+ to RING and rest goes to Shield or (ground) ??
* I was told - should be ground but I tested both male and female sides and got no ground of L and R wires .. only the 2 black next to each other give me continuity (ground)







This is a continued effort for this post that I will update/videos once I figure it out

Here is the link to the Factory Manual for your car. You will need Section AV (though I recommend downloading the entire manual) : 2015 Q40 FSM

Based on what I think you are looking for:

Hope this helps.

 

Nice! Thanks! KK so owners manual is different then 'factory'

 

No problem.
The OWNERS MANUAL tells people how to play with the different bells and whistles of the car.
The FACTORY SERVICE MANUAL (FSM) tells us how those bells and whistles are put together.
Good luck with your project.

 

UPDATE: I think it's this GOD awful fuse box "IPDM E/R" ... I like how they hide it next to the battery like a buncha jackA$$es ..Props to you car people this stuff is complicated ... I had to lookup what the hell a "front door switch" was for the AUTO ACTIVE TEST... (its the little door button on the door frame that detects the door open/close ... )

Reference: FSM/Q40/2015%20Q40/exl.pdf ( page 15 ) https://rmccurdy.com/.scripts/downloaded/nicoclub.com/

I also mirrored that URL you sent ... I would not mind being a mirror for that stuff for all the cars.

THANKS! Everything worked now I just gotta figure out why the Rear Tail lights are not on but yet the backup cam is fine .. check the FUSE box near my left foot in the driver sides and the one next to the battery no luck ;/ I also lost the nighttime 'glow' from the clock and the AC buttons .. may have something to do with that ... ill look definitely look at the FSM and go from there thanks again!
