I have been using the Cruisemaster for business travel and was canceling trips because I could not get into airports with GPS only approaches with my old single VOR/ILS setup. I have added IFR GPS capability and ADS-B in/out. I have installed a Garmin GNS 650 GPS, GTX 345 ADS-B transponder, a PS Engineering Audio Selector/Intercom, and a CGR Engine Monitor. The transponder sends traffic and weather to my Ipad. The GPS and the engine monitor share fuel flow and location information to provide range/reserve fuel information.
It is not a glass panel but it should help make the “go” decision even when the weather is not perfect.
