David Simms: Metra and PAC steering wheel control interfaces are essentially the same.
Plug into the same 1/8" plug on the back and you have to splice one wire
into the wiring under the steering column with either brand. You then have
to program the interface. I thought the PAC had better overall reviews from
experienced people, so I went with them over the Metra. In reality, both
are probably made in the same factory in China.
1028jesse: Ok I got a Pontiac with onstar. Bought the vehicle used came with an after
market radio already installed. Steering wheel controls don't work plus
onstar does not work. What do I need to make them work?
David Simms: With the Axxess GMOS-04 interface I installed, the rear controls work. I
didn't try to PAC OS-2BOSE, so I can't tell you if the interface you have
will work. Sorry. I didn't read of much success with the PAC OS-2
interface, so I went with the Axxess. However, the PAC SWI-PS (Steering
wheel controls) works like a champ and was reviewed better than the Axxess
calirider209: So why do you need the Axxess and PAC?
David Simms: If you have a Bose system (factory amplifier), you have to use the axxess
thing, unless you want to run wire from the head unit to each speaker.
There's a standard harness on Amazon you can use for GM trucks without
Bose. It's about $15.
David Simms: Perfect...depends. I do get interference, especially here in Alaska. My
cell phone, if it's within 6" of the unit will cause noise and will cause
the 'source' and channels on the radio to change at random...so the slot
under the unit is useless to put my phone there. Other than that, I've had
no issues with sound quality. Check your connections.
David Simms: The PAC SWI-PS is for your steering wheel controls.
Ryan Schommer: Where did u get and how much was the dash kit?
412arch: You are very lucky. I have a 2005 Tahoe with bose and all the goodies along
with rear dvd and stereo controls. I've tried many times to make the Metra
class 2 data bus work without success. I have sent it back to Metra twice
with the last time coming back with an explanation that I shouldn't hook up
the second trigger wire. Everything would work except the rear speakers and
dvd sound. I truly hate the factory radio. If I get the time I may try
again. Nice video.
tvfreakful: Do you mean audio plays through rear seat audio but there is no controls
except volume and can only listen to what is playing through unit
zombie13studio: Metra 70-1858 - it's on Amazon for $5. Search for: "Metra 70-1858 Radio
Wiring Harness For GM 88-05 Harness"
David Simms: Thanks, glad this helped. This is the reason I made this video...I had a
hard time figuring this out myself and I didn't want to pay someone to do
something I could do myself.
David Simms: Check the volume of the side of the interface. Tiny knob.
Armando Herrera: You could have also used a metra steering wheel control interface adapter
that simply plugs to the back of the aftermarket stereo and programs itself
to the controls. The only thing that sucks about taking that route is that
not all aftermarket decks come with the connection in the back for it.
Granpa Ernie: Hi David, I have 05 silverado that had the bose 6 disc cd player. The
question i have for you is do you have the rear fold down screen for
passengers to watch dvd's. clean looking. thanks. GranpaErnie.
David Simms: Need the Axxess to retain On Star, factory amplifier, and door
chimes/alerts. Without it, you lose all of that and would need to run from
head unit to speakers. Some people would be cool with completely losing
door chimes and On Star, but I wanted to retain both - even though I do not
currently subscribe to On Star's service. Chimes are nice if you leave your
lights on. The PAC retains the steering wheel controls. Much more conveniet
than the remote.
David Simms: Have to add it in.
David Simms: Amazon...$15. Search for Metra 99-2009 Single DIN for GM
David Simms: About $60.
MadMajd1583: oh ok thanks alot
kyleb395: i dont care about the door chimes or anything, but i cant seem to find a
harness to use without buying this axxess thing. how do you wire it without
MadMajd1583: Hey man just a quick question, how did you manage to make the rear seat
audio controls work? I'm trying to install a new double din deck in my 07
H2, and even though i dont care about the back audio controls, I still want
everything to be functional. Please let me know what adapter you used. I
have the PAC OS-2BOSE interface, if it helps. thanks
VVhiteHouse: Is that adapter needed? I don't care about door chimes and i don't have
dylan hyde: why didnt you get a deck with built in serious radio man way cleaner
MadMajd1583: Thanks for the quick reply. So, if I install the PAC SWI-PS, the rear
controls will work?
David Simms: If anyone has questions, please post. This was not simple to figure out
what I needed to install. Wiring was confusing as well.
23ferraricdg: Okay thanks i got it to work now i just noticed the little blue screw on
the lil box the volume was down ,so i fixed that , how much did it cost you
to put the steering wheel controls?
David Simms: Maybe $250, Max.
David Simms: I ran a SWC through the dash and under the steering column where it splices
into the wiring harness. I wish I would have made a video of the complete
install, but I was short on time and simply forgot. The SWC has an 1/8"
plug that goes directly into the rear of the stereo, so it's a very simple
install. Sorry, I've been moving (to Alaska), so not much internet until
the past few days.
Jose Gomez: May you please tell me were you bought the stereo mount or what is the
brand of it? Having trouble finding it?
Jose Gomez: Thank you
Norman Smith: Hey there.. I have a 05 hummer h2 , Im thinking to get an aftermarket
stereo using the PAC os-2cbose & axxess ASWC but I don't know if I'm gonna
need a harness to plug the steering w.c. of the truck , to the ASWC . Are
you using something like this? Or how did you do the job ?? One more, where
is the swc module ?? Thnx
David Simms: I do now, replaced everything and added a backup camera. At the time, I had
multiple things that I could plug this same Sirius tuner into (home stereo,
camper, etc), so it made more sense. I don't get Sirius signal up here in
Alaska since I moved, so I took it out and put the XM tuner into the new
head unit and hid it under the console.
MXSHOWTIME007: did you have to buy a steering wheel interface kit for the volume to work
with your new head unit or did it just work?
David Simms: Correct.
David Simms: José - I got it on Amazon. It's made by Metra, but Scoche also makes one
jewllake: did your truck not have the XM tuner? Or did you want Siris. Siris used to
make a kit for the GM trucks which would plug into the back of the stock
radio, or in your case now the back of your adaptor harness..... clean
David Simms: If you have Bose...it doesn't matter if you want chimes or not, OnStar or
not...you need the adapter...unless you want to run all new speaker wires.
David Simms: I do not have a rear screen. Since this video, I installed a Pioneer
AVH-4400BT which has a video output for just that. Instead, I have a Sony
or Jensen 2-screen DVD player I put in the rear, that way I don't have to
listen to what the kids are watching in the back and I can pack it away for
normal day-to-day operations.
David Simms: No, the Axxess GMOS-04 (in lieu of the PAC OS-2BOSE). The rear controls
worked for me. I do not know the differences between the H2 and Silverado,
but they're probably minimal, if there are any differences at all.
eldergow2: the only video and description that actually helped me thanks alot bro and
nice clean set up
Mcgubber: My radio turns on but it doesn't play
23ferraricdg: Does it sound perfect? I recently installed mine its a Escalade with the
bose system and all but once igot done with it , the sound didnt sound so
good , i bought the gmos-04
