I know that this unit originally used a GR16 antenna, which is no longer made. Is there a more recent replacement that will work with this unit? I bought it here on BBC quite a while back, and just got around to hooking it up. The unit works except for GPS, the seller sent a GR16/4 puck with it (which doesn't work with this unit). I doubt that I will be able to find a used GR16, so looking for the replacement. Thanks.
The AS GR50 replaced that antenna and is discontinued also. The AS GRP is the current version.
There is a restriction for the AS GRP as it will not work with the AS INTERLINK and this is also a limitation:
Software must be 6.300 or higher for the Humminbird system to be compatible with the AS GRP GPS receiver.

Thanks Wayne. I think the latest update for the 797 is only 5.4 (or thereabouts). I don't care about the interlink, but it seems a shame to not be able to continue to use the head unit that otherwise works fine.
