Far as I know, any. All that harness or connecter is, is a way to pass your GPS input to. I think it's just speaker wires and the hot lead if I remember correctly. Been awhile and I never was in there myself so don't hold me to any of this. I had a 650 Garmin and now a 590 Garmin and that harness never changed. I remembered the guys name that makes it, Dave T. Pilot. He also has a Facebook page here
. You should be able to track it down now.
Here's another link
that should help but it looks like you'll have to use the Facebook page to get Daves email address and sent him a message as it looks like all his links are broken for whatever reason.
