Here are a few suggestions for the future Garmin GPS-596...
- flat panel package, one-inch thick (max, including battery)
- replaceable Li-ion battery pack; optional AA battery pack
- a five-inch diagonal screen (as on the 530)
- landscape or portrait viewing select
- XM weather and radio
- higher resolution
- faster processor
- ability to download text (NOTAM's, weather)
- traffic (independent feed; patch from 330? ADSB? over the XM?)
- single power, XM, GPS antenna cable connector leading to a molded
"strip" connector for individual antennas?)
