First off, thank you all for your patience and assistance, I could NOT have gotten through all the choices and possibilites without you.
I've decided to go with the SEAMLESS USA buygpsnow.com package BUT I have one final question...
is the GPS receiver (BT-338?) in this combo pack:

the same as this GPS receiver (BT-339?):

If they are different, is it that big of a difference? They appear to both be SIRFIII the only diff I can even find in their specs is one is listed as running for 17+ hrs and the other for 15+ hrs...
THANKS AGAIN GUYS!
