I graduated from a GPS 90 to a Garmin 295 a few years ago and I think its the Dog's sphericals.
The re are three minor niggles however.
1: Its really too heavy to mount happily on the yoke of our Arrer as it vibrates so much you need two hands to hold yoke to read the screen (Yes, we've had the prop dynamically balanced).
Goes on the coaming instead with Velcro.
2: It eats batteries: (2-3 hours). We have a power supply from the a/c so this is not a problem but might be for the jobbing hirer.
3: Colour screen is excellent for fine detail, but it struggles in strong sunlight.
Also has the facility for extra squids (shed loads of extra squids as it happens) to convert into a car usable GPS with full database for the whole of Europe.
Just my two pennorth, but I must say, having seen the 196 in action, that looks like an excellent (and cheaper) buy.
Safe flying
