Summary: Solid piece of hardware. The screen is clear and navigation is pretty intuitive. I bought it only for the electric cord, which comes with a special plug and a small speaker at the end of the cigarette lighter plug, and without which the device is inoperable. You can't find this cable elsewhere, since it's been discontinued. Could not use the MP3 hard drive, since the unit doesn't have its own battery and I do not have a 110v to 12 v cigarette lighter converter.
Summary: Buyer Beware!!! Lowrance no longer supports the Iway 500C or 600C in any way. No repair or repair parts are available. Lowrance no longer supports software updates and there is no more map updates past Q1 2010. You can no longer get the main power cable/speaker to plug into the lighter outlet to power the unit. In it's day it was a great unit but when it fails you have to toss it in the trash. Lowrance will not honor warranty on any units.
Summary: My husband has wanted one and this one was the best deal!!! It didn't come with everything that was needed to download music and connect it to the car speakers, so I did have to buy those separately....That was a little disappointing, because in the description that was not stated...So ask lots of questions.....
Summary: The Iway 500 is a very good product i can find the routs that i need and very good directions. When ineed fuel orservsie i can find them with the Iway. It is a little large for the car but just right for the truck .I do like the larger screen and ease of use.
Summary: Once you get past the size and weight of this unit, it is without a doubt a pleasure to own. Always accurate, and relatively easy to use. The weight is a little cumbersome, but it makes up for it. I give it a 8 out of 10.
