C-80 to E-80 Classic

About 6 months ago, I started having problems with the C-80's power button. Some contact cleaner, cleared things out, until last week. The screen went blank, had to do a Factory Reset to bring it back on-line.

So, I found an E-80 to replace it. Now the fun starts, I have the RS130, which was connected to a 5 way R52131 Convertor (All in E22158 kit), then to the C-80, via a A22164 cable (ST1 to STNG).

After installing the E-80, I purchased an A06061 cable (ST2 to STNG). It doesn't see the RS130. Now I see that I need a different 5 way connector, A06064.

What is the difference between the two convertors? I have the A06064 convertor on order.
