I ended up selling my Magellan because the customer service was so bad infact it is probably among the worst of any company i ever dealt with.
I went with a Lowrance who had much better service although they tend not to be too technically minded when it comes to dealing with problems.
Garmin is my latest unit and I had to call them on the first day of my new unit I had a 30 minute wait but when I got throught the staff were very knowledgable and helpful. I woud never go back to a Magellan. They even had a design fault in their Meridian's where many would have a loose battery door causing water to get into a waterproof unit. Thousands had this problem and Magellan wouldnt do a thing about it.
