Pros: HDMI, VGA, good memory. I have XBMC installed, and have XP running on it as the OS. The DVD drive runs nicely using the provided drivers.

Cons: Getting resolution on HDMI to run at the correct setting for an HDTV can be problematic at first. Also, getting the HD Audio to be set correctly in XP is frustrating, as the XP drivers install software that provides a second location to set speaker/uadio settings. Can be confusing.

Overall Review: I should have ensured that I had at least SP1 for XP before installing the OS, as the 320GB drive has been partitioned to be 128GB or so. Limitation of XP, not the system.

Pros: Good navigation, iPod connection works fine for music, bluetooth pairs very easily.

Cons: The mic is not very good for picking up voice during a phone call. Also, the navigation system does not include all of the Point of Iterest items that a Garmin or TomTom would have (gas stations, etc.). Finally, the iPod navigation is relegated to local selection of playlists and songs via the iPod click-wheel. Need to keep playing with it to see if there is a workaround for this.

Overall Review: Basically, it's not a bad selection for a radio with built in GPS. However, as seems to be the case around the holidays, most of the local car audio places in town are suddenly offering the same system for about $100 cheaper than I purchased it here.

Pros: Very quiet, excellent use of space. The ability to put in 4 drives is a real benefit.

Cons: When first installing the drives, the second 250GB drive I installed only registered at 31.5GB. The only way to make effective use of the drive was to install it as a master drive in the thrid drive position. The drive itself is fine.
