GPS question

[Wryel]

Sorry if this should go elsewhere or if I'm being a n00b....


Will any GPS unit work on foot if you have the appropriate maps?

Its the SirFStar III reciever, it comes as part of a phone, (didn't post in MP as that was the only question I had) - would it depend on the software I install ir was that what you were implying?

Thanks!
