Summary: I'll keep this short.

The Pharos hardware is great; fast, accurate, flexible (CF, Bluetooth, cabled), compact.

The Ostia software is great; easy to use (love the \"Home\" and \"Auto Re-route\" features), fast, intuitive (after reading the manual to understand the icons).

The Map data… well that is a different story. It is old and inaccurate (missing highways and major streets that have been in place for 5+ years; and yes, I did download their “latest” maps via “Smart Maps”).

Bottom line is I do not trust their maps to get me to where I want to go in a city I do not know. I’ll just use the Pharos hardware with Pocket Streets & Trips or Mapopolis.

So my advice is to just by their hardware w/o Ostia and get another Navigation Application with reliable map data.

Summary: I had read previous user's review before purchasing this receiver. It seems there is a serious drawback on the software. So I had prepared the worst situation--buying a other software if it really happened. After trying the software which comes along with the receiver a little, I feel it's a pretty good software. 3D view, voice guidances and a bunch of friendly features. I live in Queens, New York, at least the map information is precise in this region.
Just the Holder, I really hate it. terrible and awkward.
