No. Pressure altitude can be passed to the MX20 through the GX series of GPS units' serial data stream. This feature allows one of the four MX20 serial ports to be freed for other purposes than a dedicated altitude encoder input. For this feature to function, the GX GPS muse be running version 3.2 or newer software. In addition, the GX GPS must be wired and configured for altitude input from an altitude encoder. The GX serial output should be set to 'extended' mode for the altitude to be included in the data stream sent to the MX20. The altitude source port on the MX20 should be set to the same port that the GX GPS is connected to.
As of November 2004, the Garmin AT MX20 Multifunction display will only interface to the RDR-2000 (ART-2000) and RDS-82 (RS-181A) sensors for radar display as a radar/traffic upgrade available for existing MX20 units. The traffic interface of the MX20 is compatible with Ryan TCAD and Goodrich Skywatch traffic avoidance systems. Currently, UPS Aviation is indicating that there will be only one upgrade available for existing MX20 units. This upgrade will include the addition of both radar and traffic interfaces. The cost of this upgrade to existing MX20 units will be $8200 (list price). As mentioned, three versions of the MX20 will be available once these interfaces are completed. The basic version's list price will remain the same ($7295). This does not include the traffic and radar interfaces. The traffic version of the MX20 will include all the features of the basic version but will also include the TCAD/Skywatch traffic interface as mentioned above. The price for this traffic version will be an additional $1200. The radar version of the MX20 will include all the features of the traffic version but will also include the weather radar interface as mentioned above. The price for this radar version will be an additional $7700. nal $1200. The radar version of the MX20 will include all the features of the traffic version but will also include the weather radar interface as mentioned above. The price for this radar version will be an additional $7700.
Yes, the Garmin GTX-330 will interface with the MX-20 to display traffic information as long as the MX-20 has the traffic option/upgrade installed.
Newly Overhauled parts obtained from Garmin are designated with an N in their part number. This usually follows the 010- in the part number. As with most Garmin 010 part numbers, the N part numbers are for ordering purposes only and do not actually appear on the dataplate of the unit.
Yes, for the most part the Garmin GMX200 Multifunction Display will directly replace the original UPS Aviation / Garmin AT MX20 MFD with minimal installation changes. Both MFDs utilize the same dimension mounting tubes and connector styles; however the mounting tube part numbers are different. The mounting tray would need to be replaced. The GMX200 utilizes a configuration module that is located in the backshell of the main connector. Therefore, certain provisions would need to be made to include this config module in the connectors and programming of the configuration module. There are also some minor details relating to the MFD interfacing to a CNX80 or GNS480 if applicable.
