Install a Clarion 2nd Gen. radio (8-pins) and retain 1st Gen. (6-pin) remote control without rewiring.
When replacing a 1st Gen. 6-pin radio (e.g. CMD4 etc.), with a 2nd Gen. 8-pin radio (e.g. CMD8 etc.); and retaining the 1st Gen. remote (already fitted) requires the CCUMRA1 adapter cable. This is adapter cable is required because all Clarion 1st Gen. marine radios, wired remotes, and extension cables manufactured between 1998 to 2008 have 6-pin connections. As of 2009, all Clarion 2nd Gen. marine radios (e.g. M309 etc), wired remote controls (e.g. NW2 etc.); and remote extension cables (e.g. MW-RXC-RET); all use 8-pin connections. To replace a 1st Gen. radio (6-pin) with a 2nd Gen. radio (8-pin); and retain old remote control (1st Gen. is impossible without rewiring, but for less than $50, the CCUMRA1 adapter cable makes it possible to upgrade the radio and retain the 1st Gen. wired remote control on upper deck, transom, dive platform etc.
Warning: If the remote has an LCD screen (e.g. M301RC etc.); the display function will go
blank; but the buttons (e.g. FF, RW, Pause, Play etc.) remain functional.
