In 1998, I got a Garmin GPS 12XL. It has no database, but has a capability to store 500 waypoints. The only limitation is groundspeed less than 999 knots...haven't been there, yet. I have the same problem with the window heating and I need to use an external antenna. For the same price, I think you can now buy a Garmin GPS III Pilot with updatable database. I maintain my database with a freeware program called EasyGPS and transfer it from my PC to the GPS...much easier than entering points and routes in the GPS itself (http://www.easygps.com/). Fly safe.
Yes if you get a Garmin 195 you will probably be very happy with it. The 195 has a built-in internal antenna and also has the external so you can set it up on the "dash".
The 195 will work in the -9 very well.
You might check with capt. Key he uses a cheaper Garmin sometimes and it seems to work for him.
(cant remember the model number)
