GPS/Marine Radio for Cobalt '08 - 242

[Stonehauler]

I need to replace my old GPS (Garmin 478) that's finally given up the ghost.

I was hoping to get some recommendations. I am willing to upgrade my marine radio as well if it increases functionality.

Looking for a system that has good depth markers and GPS placement with maps of US coast - specifically Delaware river, bay, C&D Canal, Chesapeake Bay and rivers that come into the northern Chesapeake. If we can also get maps of US lakes as well, that is a bonus.

My current system is mounted on top of the gauge pod, so I don't have a lot of room between it and the windscreen, so I can probably fit a 6, MAYBE a 7 inch display in there.

Removeable is preferred, but if not a permanent mount is ok.

I am not an angler, so I don't need fancy fish finding capabilities.

Tide tables are a plus though, but I can get that on my phone if needed.

My radio is a Standard Horizon phantom PS2000 radio with a remote handheld unit and 3 db antenna (thinking of upgrading anyway to a 6 db antenna)
Ideally, both radio and GPS unit work together.

Thanks in advance all
