Ok so u wanna buy GPS...it all depends on wat kind of GPS u wanna buy. the easiest to use is Garmin and thats wat i am using since last year...no problem up to this time but every month i have to update it online for new street and new stuff like hotels, business, complex etc. DOnt buy the one in which u have to insert map SD card those are crapy one online updating is better .Garmin has all kind of gps even with the inbuilt MP3 player which can hold up to thousand songs and u can uploads pictures but u will need high memory capable SD card. U have two option the flat GPS or the thick one flat looks nice but thicker is ok and the thin is expensive than thick. if u would like to buy better one go for garmin...but before buy do some researc go online and go to different store talk to seller coz this is not the thing u buy today and buy another next month....Good Luck
