In my lap top I have both the garmin,(sucks) and streets and trips,and thru my sprint phone,I also have gps.I like my phone gps as well as any,but when routing myself or checking the miles compared to what Ive been offered,the streets and trips is great.You can also get it to use prefered roads,that I cant do with my cell,but after I go off route,cause of useing my own diretions,the phone will change to the way I'm going.My main reason for GPS is just for local directions,I can read a map so as far as needing a GPS to get me from one town to another,it would just be a useless.GPS,its just a toy.
