Metra Access ASWC-1 programming issues
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,
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.

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.

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.
