Garmin Mobile XT.
I have "Garmin U.S. Recreational Lakes with Fishing Hot Spots".
It even list a lot of small ponds. Was quite happy with it.
I hear you can find Blue charts also.
"(Copy/Past from HERE) BlueChart g2 Vision offers the high detail charting of BlueChart g2 plus high-resolution satellite imagery, above and below the water 3D perspective, auto guidance technology, aerial photographs for real world reference and coastal roads with points of interest."
