I have a 2 fold question.

First, has anyone successfully used one of these guys:

I tried to register on their website forum, but the admin has to personally approve all logins or something. Reading the comments from others on the forum it seems like there is some fine detail to which stereo you have, etc.

I have a 2003 acura cl-s w/ a factory 6-cd changer.

Second, the stereo controls on the steering wheel are totally f-d up. It has been this way a while now, usually any of the buttons will have a random function (volume up/down or change), but mroe often any of the buttons has the change CD function. It seems like there are sweet spots when the steering wheel is rotated a certain amount that the buttons work like they should (I noticed this at the gas station last night).

I read about this before and someone said the contacts might be dirty. I took the housing apart and cleaned the dirt off the contacts and still is not working. Is there a solvent I should use? There is a lot of clear grease on the contact surfaces. Suggestions please -
