Metra Access ASWC-1 programming issues
Hello, installed a Pioneer AVIC 8000 in my 2005 SL55 today using an OPTI-1 module. All went well until I tried to program the Metra Access ASWC-1. I followed the instructions and pressed the volume "up" button when instructed to but, the volume continues to climb even after I let off the button. The volume down button on the steering wheel does nothing. I can lower the volume by pressing the volume down button on the head unit but, as soon as I let off the volume down button the volume increases again.
I didn't play with it too much tonight as it was getting late. I'll try resetting and programming it again tomorrow.
Anyone have any ideas what the issue may be?
Thanks,

press and release volume rapidly. relearn the aswc1... takes 2 -3x sometimes
this could help, same procedures after you made connections http://contentdocs.installernet.com/...icle/12534.pdf
where did you grab can wires audio gateway? or ac controls?

Switched power for the OPTI-1 I drew from the red/yellow wire from the original comand connector. I also grabbed ground here.
For 12+ constant I used the cigarette lighter.

Thanks for your reply. Was just worried if I did cut the connection at the Gateway to tie in the OPTI-1 I might be affecting another sub system tied into the same CAN-BUS. Interesting that you tied the switched power and ground into the original command connector. I was thinking I would use that for the new HU. May I ask where you connected the switched/constant and ground wires from your head unit. Thanks again. Terry

Forward of the shifter below where the heater controls/ash tray are located there is a module mounted to the tunnel. There is a bundle of wires grounded to the chassis through one of the 4 bolts that mounts this module to the tunnel. That is where I pulled ground. For constant 12v I pulled this off the cigarette lighter power wire. For switched power I believe I used the Comand connector for switched power to both the OPTI-1 and the stereo as well. The switched power to the stereo is simply a signal reference to switch on the stereo, it does not actually power the stereo. The +12v constant is the power wire. I was comfortable that the switched from the Comand could power both the OPTI as well as act as the switched signal for the head unit. Two weeks now and no issues at all. If you are not comfortable with this arrangement you could likely find switched power at the fuse box behind the passengers seat or, the fuse/relay box under the hood at the rear left corner of the engine bay.

I used the ground lug next to the Gateway to ground the ASWC-1, and IIRC I pulled switched power from the fuse box behind the passengers seat.
EDIT: Note I have an R230 SL55. I see you own a CL500. If that is the car you are installing the new Head Unit in, the wiring and location of some of the components I've mentioned may be different in the CL.

Can you comment on whether the Metra Access ASWC-1 allows aftermarket NAV or TEL information to be displayed on the instrument cluster? I have a AVIN head unit that comes with a cheapy pre-programmed canbus decoder that works fine for reverse, and steering wheel controls, but doesn't do much else. I'd love to have bluetooth track information on the instrument cluster, or navigation information as well.

From what I know it does not. It will control changing stations (up/down) and changing volume (up/down). I removed the old analog phone from my center counsel and everything for the phone is controlled either by the cell phone itself, voice command or the Kenwood touchscreen head unit. The Nav is controlled through the head unit as well. When I scroll through settings in my original dash display TEL/NAV are blank and have no sub menus. Hope this helps.

For anyone with an early W215 / C215 that finds their way here via search, I was able to successfully get the ASWC-1 to function with a new Pioneer head unit. The CAN bus on my 2000 CL500 is GREEN and WHITE in pins 15 and 16 in the C2 connector.
Connect WHITE (CAN Lo) to Blue/Pink on ASWC-1 harness
Connect GREEN (CAN Hi) to Pink on ASWC-1 harness
Programming took a couple of tries, but was ultimately successful.
A word of caution, the "popular" pinout diagram for COMAND 2.5 that is prolific all over the internet appears to be incorrect for an early W215. I have no idea what it's really applicable to.
