What is this aftermarket radio problem thing ? I have an aftermarket radio since last year, and only have lost the antenna signal and the steering wheel buttons use since then. What is the problem you are describing coming from ?Your log is still showing a lot of communication errors. Do you have an aftermarket radio, as they are often installed wrong and can cause this problem.
Other then the radio, I would check recheck the wiring. That brown wire is frail, thin, and often the water damage seeps up past the end, into the brown wire under the first several inches of insulation.
