Has anyone tried using the 522C in their truck/car? It would be great if it was possible but 35 bucks for the power cord as an experiment doesn't make sense. Wish I tried mine before installing the power cable in my boat. I am mostly wondering about the satellite to internal antenna reception.

nobody has tried this?

yes, it wil work. but you need keep your unit close to the window for good gps reading.

Just out of curiosity, why do you want to install your 522 in your vehicle? Are you planning on driving it into the lake?

not if has a hot spot mapping card for that region that he going to. it will show all the main and minor roads. etc. lots people do this. but its not turn by turn directions.
