Thanks for sending that to me, Brett PMed me the same review. I've read it online just trying to see if anyone has actually used one. They have a pretty cool function with having the satellite photos built in.Here is a review...

Can you use the PN-40 in your car as well?I have a PN-40 and find that it is very good. Was a toss up between the Garmin Colorado and the PN-40 and chose the 40 because it was a better overall unit. I think that the Garmin may have a better map set for marine use but with the ability to not only download all marine Noaa charts but also aerial photos and satellite photos the overall use is better and boy does it connect quickly.
