A couple months ago I bought a Garmin Nuvi 200. Have it with me all the time I am driving. There were a couple times the unit beeped and I got the message "Satellite Signal Lost". After a period of time and a couple resets it starts working again. I have never lost the signal on the Lowrance on my boat and was wondering if this is common with a car one or is mine defective? Update: The couple times this has happened was on the open road. Once on the Ohio Turnpike and the other just yesterday between Akron and Youngstown.
