Any brand of unit that has GPS will have map capability .... some come with a map card, others come with a base map & card slot for a map card, while others come with the ability to make your own maps. Their pricing will reflect what they have.

If you want Side Image ... be prepared to save some money & get the biggest screen you can afford.

Keep your eyes on the Personal Classifieds Forum & you may get a good deal on a used unit. They pop up on there from time to time. Or if you just aren't sure what you want, but you are sure of what you need it to do & how much you can afford .... you might want to contact Brian@BBGMarine (member's screen name) and talk to him. You can PM him, or look up his contact info in his signature line ... and you can find that in his post on the Member Sponsors Classifieds Forum.
