Rockwell Collins has been a leader in navigation radios and continues it’s proven track record with 3 models of Pro Line 21 navigation receivers, the NAV-4000, NAV-4500 and the VIR-4000. The NAV-4000 includes the VOR/localizer, glideslope, marker beacon and ADF receivers in a single package. The NAV-4500 is identical in size to the NAV-4000, but excludes the ADF receiver. The NAV-4500 is intended for installations offering a single ADF receiver as standard with a dual ADF receiver as an option. If you are looking for a VIR 32/432 replacement then the VIR-4000 is what you want. The VIR 4000 was designed to be a direct replacement for the VIR 32/432 keeping in mind some of the legacy interfaces like CSDB.

There are many radio tuning options to choose from, please consult your Rockwell Collins dealer to choose the tuning option that best fits your needs.
