dear Ken,
thanks for your advice.
I sent 2 email to stbann@cdadapter.com (Ann Marie ?) without answer (yet).
I saw in cdadapter site different type of conversion kits.
RMC-MP3 allows 200 selections without any modification for my Rowe R-91 CCC 40777305
RCU-MP3 allows 600 or 1,000 selections depending on CCC firmware version, may be a EPROM change will be needed.
CD100MP3 allows 10,000 selections, this kit works with CCC 408322XX
Do you know if CD100MP3 kit could be installed in my R-91?
How may I know the CCC firmware version?
Any other adapter in the market?
Thank you
Claudio
PS, The switch was adjusted, and every things work find :-)
