I would recomend u buy GARMIN 396 . Though a lill expensive , but it can be used for multiple purpose . I have been using it for last 3 yrs , and could not think of using anything else . Wide screen , voice nav  , color screen .U might check it out . Go to www.garmin.com . you can infact have a sattelite radio deal on it . Give's ur traffic , weather and whole 9 yrds .
