Summary: I purchased the Lowrance iWAY 500c as a birthday present for my directionally challenged wife. Her mother has a Garmin Nuvi that my wife had been using and loving while on vacation in Florida.
Summary: Our unit died just before the warranty was up, I sent it back ($50 because of weight and insurance). They sent me a refurbished one, didn't work. I sent it back (on their dime). They sent me another refurbished one; it stopped working after two hours. I sent it back; they sent me a new 600C.
