Need recommendations for a GPS unit for my pontoon boat

[OK Toon]

I don't fish from the boat so I don't need the fish finder, 2D, 3D or HD imaging of what's under the boat (fishing is done on the dock). I currently use a $10 Navionics app on my smartphone which works great, but since the phone screen is small, it's hard to see sometimes. Even harder to see in bright sunlight. I would like a unit that shows me where I am on a lake as well as the depth contours of the lake - it would be nice to know water temp and speed but I'm sure that is part of any newer unit.

As you can see by my current solution I'm cheap so I don't want to spend a grand on a fancy plotter. I would just like a larger color screen to show me where I am and depth information/contours, water temp and speed.

I currently have a HB Matrix 15 that came with the pontoon boat when we bought it from PO. Unfortunately it doesn't have the transducer to read water temp and the depth isn't always acurate when underway.

Any suggestions??

Thanks everyone!
