GSR56 costs
The GSR56 is going to be about US $9.4K retail, plus installation costs. Annual subscription for weather and voice services is US $1200, and data rates are based on useage time, not data size. Typical voice calls are US $1.30 minte, and typical weather received every 15 minutes for a 100NM corridor along your route will cost around $8/hr. All subscription and call charges are billed through Garmin - no separate charges back to Iridium.
