I have a magellan xl. I am 62 and the exta large sreen is a help. it runs on aa batteries not aaa. I find it very accurate with having possibilites of obtaining 14 sats. many time i have been within 1or 2 feet of cache. you also may want to add lastest version of direct route. I went from new orleans to ruston , la. and all around with no difficulty. I have used the back light on from sun up to sundown without changing batteries. i use regular rechargeables. i owned a sportrak pro before getting this one.
