This unit was removed from a 2004 cirrus sr 22 aircraft being parted out. It was removed with about 320 hours on the unit. It was in perfect cosmetic and working condition when removed. It includes the midcontinent gyro, which when combined with the unit sells new for somewhere between $15,000 and $16,000. It is a compact navigation system designed primarily for ga applications. The sn 3308 has an installed base of some 4,000 units. Sandel continues to support the 3308 with maintenance, parts, database updates and product support.
Sandel and garmin have worked together to create an extremely simple interconnect scheme using the arinc 429 digital data bus. A single gns 430 interfaces to an sn 3308 with a total of only four wires! (a dual gns 430 configuration may require a small relay, but is still an extremely simple interface. ) all vor, ils, gps and map data, as well as annunciators, flags and switching commands are handled via the arinc 429 bus.
With the arinc 429 interface, nav source selection can be made from either the sn 3308 or the gns 430. Pressing the nav button on the sn 3308 will command the gns 430 to switch between vor/loc and gps. Likewise, pressing the cdi button on the gns 430 will change the nav display on the sn 3308.
The map presentation on the sn 3308 will include waypoints sent from the gns 430. It will not include topographic features such as roads, water or railroads.
A complete description of the sn 3308/gns 430 interface is also available.
Note that the sn 3308 uses the same ports for both arinc 429 and king serial digital dme data. With a single gns 430 connected, one input port remains available on the sn 3308 for a dme input. With dual gns 430s both connected as primary nav sources, a digital dme such as the kn 62 or kn 63 cannot be interfaced. An older analog style dme may still be interfaced in this situation, however.
All units shipped prior to this release are eligible for a free upgrade to this new map/database software. The only requirement is that the sn 3308 be at hardware status "mod 1" or "mod 2". Units shipped from the factory after mid march 1999 are at this hardware level. Older units will be modified at no cost, but must be returned to the factory. Turn around time is generally 3 days. Please contact the factory at 760 727 4900 before sending in the unit to ensure a quick turn around.
If your sn 3308 is at mod 1 or mod 2 hardware level, the map/database is a software only upgrade which can be downloaded from this website. Owners of older, pre mod 1 units should return their sn 3308s to the factory for the complete hardware/software upgrade at no cost.
