I thought you had one you needed the booster with? It may be an issue with Serial data strength with the newer RS 5.0 from ERR. Even some of their older boards won't work with it unless you use a small booster circuit. G
That's only if you use the older ERR Cruise Commander M, clearly not the case here. I've never seen where the R2LC couldn't drive just the new ERR sound board with no other serial connection.
