Works Fine, but I Want Better

It works as described. It was easy enough to install even though soldering all the wires up is a lot of work. For the price I would like to have more detailed instructions. The mass of wires & boxes from this & the steering wheel control take up a lot of room, would have been nice to have an all in one unit. Instead of using a turn signal chime like the stock radio used this uses a physical relay to click and also adds to the mass of wiring and components that I need to try and stuff underneath the radio. There is only one potentiometer to adjust both the radio audio level & the door chimes, which makes the adjustment process more complicated than it needs to be.

Super easy install and works flawlessly!

Bought this to install a Sony double din stereo in my '06 HHR, along with Crutchfield's vehicle-specific wiring service so I wouldn't have to splice anything or run the risk of messing up the functionality of it since this was my first factory radio replacement and I had no idea what to do. Super easy install, it was basically like setting up a new computer, plug this here and this there. Was maybe like 7 connections max I had to make and that was it. Couldn't have asked for a more simple install with this. Crutchfield is the best!

Works great, but without Crutchfield techs to talk me through how this thing works, the instructions failed badly.

Too easy not to use.

Amazingly easy to install I added quick connects (getting a different radio) and pluged it right in. Everything works even the Bose amp and speakers. No interference no issues.

It certainly made things easier by using the harness. Radio controls on the steering wheel do not work now. Little disappointed there.

Took some time - but a great end product

This review is a combo review for Axxess GMOS-LAN-04, Axxess ASWC-1, and Cruchfield's Ready Harness Service (RHS). In the end, everything works and works great. It did take time and tech support (Cruchfield and Axxess) to get there. Axxess device instructions, although car specific, are not very useful if you have a problem (but tech support is). The RHS did save time and was professionally done. However, my assumption that this was going to be plug-and-play was wrong. I did need to 1) Make 1 additional connection using the Axxess ASWC-1 supplied harness for the SWC interface - the GMOS-LAN-04 instructions say to not use the harness provided with the Axxess ASWC-1. I needed to use the 3.5mm plug adaptor and connect it to the SWC wire of the head unit (this is in the Axxess instructions but after it says if your HU has a 3.5mm interface - just plug it in). 2) I had to cut a wire on the GMOS-LAN-04/ASWC-1 interface - This too was in the instructions but thought it would have been done as part of the RHS. 3) I changed the connection to the reverse sense line to a separate line from the backup camera. The RHS correctly connected the wire to the factory plug but because I have one of those rare manual transmissions, there was no signal at the plug - it would have been nice to know this was a potential issue before I routed the wires from the back. The steering wheel controls work well, but had to be reprogrammed for the correct mapping.

Makes a daunting task relatively simple. It did take a bit longer because I would have to read the instructions with the interface and then compare to the instructions with the headunit. Make sure you provide Crutchfield with your exact car setup as they do vary.

Easy does it!

No complaints whatsoever. I also purchased the ready harness which made the installation truly plug and play. A small adjustment to the potentiometer to adjust volume and chime levels and I was ready to button the system up.

Very time consuming to install and wire up. I used this with the ASWC-1 to retain my steering wheel controls. I bought an Alpine iLX-W650 stereo to install in my Pontiac Solstice GXP, and it works. I found the potentiometer to be somewhat finicky to adjust, it took me awhile to get the volume to where I wanted it without introducing a lot of clipping. I'm not sure how well this adapter would work with an aftermarket amp, but I probably won't be installing one. After installing the interface, my Alpine head unit could not detect the parking brake wire, and would not unlock the settings and bluetooth pairing. After a call to tech support, I had to bypass the interface and wire the head unit directly to the e-brake wire. Charles from tech support was very helpful.

What a pain!

Car-Pontiac solstice. Difficult install. Used help desk. They couldn't get it to work either. Decided unit was faulty. Sent new one. It worked but only after unit was manually programmed! What a pain...

Axxess GMOS-LAN-04 Wiring Interface

I bought this along with a Kenwood stereo and a month later still do not have steering wheel controls working. I have spoken with various techs on this and all of them did their best but still not working. I bought the wiring harness premade to avoid the hassle of doing it myself . This should have been just removing the old and plugging up the new but it turned into a week event with car dash in pieces sitting in the garage. Being frustrated I just put the thing back together and do without the wheel controls. Other than that it works fine.

Works as described allowed me to wire an aftermarket radio and retain my bose amplifier. I'm not sure if it does volume steering wheel controls if it does I couldent figure it out.

Could be better

Right out of the box this harness is wired up to plug into the vehicle, it works OK. What I don't like is how bulky this thing is, it barely fits into the space behind my stereo. The blinker sounds are made by a mechanical relay, which sounds a little soft. In the original GM setup the sounds are electronic, they are piped into the driver's side tweeter and sound better. The steering wheel control pins do not work with my specific vehicle. This was not written in the instruction sheet and caused me a lot of frustration and headache.

This interface does the job. It's actually a better design ( got some improvements done to it ) then the original GMOS LAN 04 from 4 years ago . Reason for 4 stars is because original failed after 4 years of work.

Room for improvement

A must if you want to easily keep On star, and warning chimes on an aftermarket HU. The blinker tone should have been built in instead of using a bulky relay to make the clicking sound. It serves the purpose, but is overpriced in my opinion for what you are getting.

Bad impedance match???

Would not permit higher volume levels from my wife's 2008 Chevy Malibu without significant distortion, even after swapping out original unit with another Crutchfield-supplied unit. Pretty sure the radio's not at fault, it works at lower levels. Review revised 5/9/12 After much troubleshooting and pulling-out-of-hair, culminating in an "aha!" conversation with Crutchfield tech support, discovered that my wife's car radio does not incorporate an external audio amp. Therefore, this interface would not work. Crutchfield promptly shipped the correct interface (GMOS-LAN-03) which worked as advertised.

Almost Flawless

The only place where I will agree with the previous rater is that this device does not allow aftermarket amps to be used. Blame GM for their audio design, not Metra for their adaptation. If you are dead-set on aftermarket amps, speakers, and head unit, then you need to be prepared to give up the factory XM, OnStar, and warning chimes, or to do a lot of work to re-engineer the GM system. This issue is not unique to GM vehicles - many modern automobiles have highly integrated audio systems and it is getting much more difficult to install aftermarket equipment! I used this interface to replace my Monsoon (Panasonic) radio that had failed buttons, with a JVC unit, in my 2007 Saturn Sky. It worked almost flawlessly. The one issue: if you like leaving your key in the ignition with the door open, the chime WILL time out, unlike the factory setup. I will have to remember to take my key out when I am fueling my car....

This unit will only work if you replace your stereo, and still use your original speaker setup, amp'd by the stereo. If you try to use an external amp, you'll loose all the features of this interface, and it will become worthless. Read a lot and get clear of what will your setup be.
