Has anyone done the Rockwell Collins Proline 21 IFIS upgrade with West-Star in Grand Junction? Specifically on the Challenger 300 but any experience with avionics upgrades through West-Star would be much appreciated.

Thanks in advance.
Really great people at West Star. We've done fms, mfd, iridium, and rvsm mods there as well as paint and interior and all of our maintenance. Neat part of the country too.
We had our Falcon 50 done at the same time as we did our Dash 4 conversion at West Star / Premier in East Alton. They did a phenomenal job on the installation of the Proline 21 and have been great with support above and beyond what rockwell can do for you.
