Hi, I'm in the process of installing a Comand APS in a 2006 W203 C-class. So far so good, but now I'm stuck. I can't find / feel the upper catches to remove the air vents. I'm following the instructions from MercUpgrades, but the picture of the catches has me stumped. Are the hooks to be inserted through the small holes at the top back corners? If so, exactly where are the catches in relation to the holes, and how does one find them? (In other words what do they feel like through the hooks?) Any easy tips / tricks in relation to these?

Many thanks

Edit: Problem solved. The tabs are in the extreme top corners closest to you. They come out quite easily once you get the hooks on them.

Use a pocket flashlight.

There are at the top just next to the screw holes.

Yeah I found them. I couldn't see them at first and assumed the hooks had to go through those two holes. Anyhow it's all done now and works like a charm.
