Pro X Hub...
The Fast Stack Pro-X Hub is designed for an IFR EFIS centric configured instrument panel and can be retrofitted to any older or newer aircraft, certified or home-built. The Pro-X Hub is compatible with (but not limited to) Garmin NAV/GPS/COM, audio panels, intercoms, moving map displays, VOR indicators, HSI’s and just about any “send and receive” Electronic Flight Information System (EFIS).
The Pro-X Hub is compact and lightweight permitting installation anywhere behind the instrument panel. Simply select the appropriate Approach cables for your avionics, plug it in and you're done. All Approach cables are Milspec Tefzel with proper gauge and shielding. Cable ends are terminated with the connector connecting the Pro-X Hub to the avionics.
