Digital 3-axis Magnetometer Heading Sensor
Unlike conventional flux valve systems, which detect only the horizontal component of the Earth’s magnetic field, the GMU 11 magnetometer provides full 3-axis vector measurements for the most precise digital indication of magnetic field strength and direction.
Good price for the value-add. I hooked this up directly to a G5 (no G3X in my plane) and it worked perfectly. I *NEVER* have to set my DG anymore! Was very easy to install (and is not as sensitive to disturbances as the install manual might have you believe). I replaced my vacuum DG with this magnetometer and a G5, for about the same cost as getting a new vacuum DG!
It is so nice powering up your aircraft and not needing to dial in your heading against the wet compass. Product is worth more than its weight in gold.
It is not included. Please see part # 11-15066.
The connector kit for the GMU 11 is part # 11-15066. To pair the G5 with the GMU 11, you'll need to run a 2 conductor shielded twisted pair on pins 1 and 2 of each connector. The shielding must be terminated to a ring terminal on the housing of the connector to function as a proper shield ground.
The GMU 11 connector kit (Garmin pn: 011-03002-00) includes the following: cast connector backshell with hardware can bus terminator 9 pin d-sub connector 9 size 20 d-sub socket contacts
The GMU 11 experimental version, part number 11-15077, is the item that you will need.
In the g3x manual under the gmu 11 section, there are detailed recommendations as to where and how you can install this unit.
Those units are part of the G3X system, so yes they will work together.
No you do not have to have the G5 connected to the GMU 11, however you must have the G5 connected to a certified GPS antenna. You can connect your GNS 430w to your G5(AI) via RS232.
No the G5 will not keep the GMU11 alive. You will need a backup power source.
Yes only one GMU 11 is required for the setup of two G5's.
