The only thing new vhf would connect to is antenna a universal connection and gps which is probably on seatalk network. I had a Ray 218 and lost my gps, I went up to Garmin 210 added a nema 2000 network. I already had replaced my chart plotter with a Garmin 7607 and it was all plug and play. Kept the seatalk as I have auto pilot and depth still on ray sea talk. I understand there are adapters to get from sea talk to a 2000 network. My neighbor replaced his chart plotter and vhf and was able to use his ray depth and auto pilot too. Check around to see if you can adapt. I really like my new radio for me it was better to replace than repair. Good luck.
