Revision A of Garmins 8000 Series (8008,8208,8012,8212, 8015, 8215 & 8500) are now available online.
No mention of the CAN interfaces so far though – but matches up quite well with the Garmin new GPSMAP 700 (721/741) series where the 12 pin sonar connector is not mentioned and the Network port is reserved for “future use”. So it seems like Garmin are keeping some goodies for later.
The quick start manual is completely garbled – but Garmin might update that – so here is that link as well
