I finished the installation, a few days ago, of a new MFD on our H41AC. It's a Raymarine Axiom+ 12 replacing a Raymarine E80 that was probably installed when the boat was new in 2007. The installation went smoothly as I was able to use the same NavPod - I just had to enlarge the hole for the larger unit.
Part of the installation involved putting in a SeaTalkNG backbone. The main reason for doing this is because my Em-Trak B951 AIS transceiver had been providing data to the E80 MFD over a high speed NMEA 0183 network and the Axiom+ doesn't support NMEA 0183. Fortunately, the AIS unit also has a NMEA 2000 output which can be easily connected to the SeaTalkNG network.
I still have some SeaTalk1 instruments (ST60+ depth, wind and speed), RS125 GPS and ST7002/S3 auto pilot but the SeaTalk1 network is easily connected to the SeaTalkNG network using the SeaTalk1-to-SeaTalkNG converter.
The first photo shows the Axiom+ installed in the NavPod at the helm station. The second photo shows E80 that was present (photo from the pre-purchase survey). The third photo shows how I enlarged the hole in the bezel to accommodate the larger display using my milling machine.
