Randall, yes the Passport is programmable (I have X turned off).
I don't know if it's upgradeable. Sending it back to be upgraded seems inconvenient though. Other than the arrows, I'm pretty sure the Passport has all the features of the Valentine -and more.

Hey baseball, do you really want to wait to see if Valentine adds a GPS feature? Can you imagine that unit being any bigger? That thing's size as it is isn't quite discreet. Imagine a "boom box" from the 80s.

AKL, I'm not saying the arrows don't work. Clearly they do let you know where the signal comes from. But it's not the "where" that makes you slow down.

I guess I just want Valentine supporters to realize or concede that arrows are nice, but merely bells and whistles.

I love this debate.
