Proceed CDD

Does anyone know of anyone who repairs the Proceed CDD Transport? Mine quit working a few years back and I just removed it from my system. I'm also not looking to dump $1100 into the repair. At his point, I really don't care if it's Levinson authorized repair or not. I just want it fixed. I'm located just out of Chicago and am struggling to find anyone in this area who repairs them. A name, location and if available, a phone number. Thank you in Advance>
