Well, I'd prefer to not use it for x-c's (as long as VOR's and such are still out there, which I assume they are since people fly these aircraft IFR all the time) but it does sound like it would be really good for situational awareness. $600 new though, eek. Also, can you attach it somewhere or does it have to lie on the seat next to you or something?
Don't be hardheaded Rose . If you get a GPS and use it a few times, you will love it, guaranteed! I have a yoke mount with mine, and it is mounted right in front of me. Easy to get to and easy to see, except when it gets dark. Then, I use a flashlight (it has a monochrome screen and I don't like to turn on the backlighting because of battery drain).
