Should be like brand new.. Most refurbs I can't tell from one new in the box.
It will take a while to get used to all the different setup options. Also, some things
you may not notice at first.
IE: if you are in the regular driving map mode, and then touch down where the
numerical data is, it should pop up a "flat" map if it's like mine. I think it will usually
show the whole route if one is programmed.
Also, in the upper right hand you see how many sat's are being received.
If you touch that area, it should bring up a detailed sky map of the satellites.
If you touch down along the bottom, that brings up the volume control I think.
Quicker than going through the menu..
BTW, I prefer the stock female voice over most the ones I've tried so far.. :/
Also.. Every once in a while you might notice that you turn it on and it won't
seem to receive any birds. I've had this happen a couple of times.
I think it gets kinda lost to the sky map or something. But when that happens
I just reboot it and then let it sit. Eventually it finds them, and then it's normal
again after that. The normal boot time is fairly quick.
But just thought I would mention that if it ever happens. Don't despair, it should
load up once it sits long enough. I thought mine had gone south the first time
that happened.

Then it finally loaded up after sitting long enough
and was normal again after that.
I update the latest sat map every once in a while. That speeds it up loading
the birds. It's free if you hook the GPS up online. Ditto for the red light cam
updates.
Probably should do mine.. It's been a while since the last time I updated it.
