 Posted: Mon May 07, 2007 2:36 pm Post subject: Garmin 496 - XM Antenna connector |
 |
|
I am installing a Garmin 496 in my Super Decathlon and the 90 degree connector for the XM Antenna has interference issues. The connector looks like a standard Mini-USB-B 5-Pin ; so I cut the cable expecting to splice on a cut cable from a standard Mini-USB-B cable.
The XM Antenna cable is 5-conductor. I’m learning by trial and error that every Mini-USB-B cable I buy and cut is 4-conductor. Does anyone have any good answers ?? All I’m needing is a straight connector on my XM Antenna.

Mine is close too. I'd call Garmin and ask.

Hi Larry and RV-List,
So far no joy with Garmin. I’ve been trying to get Technical Support to pass me up to someone with the answers but evidently Garmin doesn’t know anything about that antenna they sell and use.
To answer another question about this; I am not using the AirGizmo mount – it uses too much height and its quality doesn’t meet my standard. I have designed and built my own mounting and the interference of this USB connector is with the Garmin SL40 that resides right below the 496. My question and predicament remain. Does anyone know if all 5 wires in the Garmin GXM30A antenna are used ??? So far Garmin has been no help.

Larry,
I've had similar experience. The mini-USB extension cables I bought didn't work, which I presume is because they were only 4 wire. Wikipedia's article on USB shows (IIRC) that one of the mini-USB pins is normally not used.
If you do find a solution I'd be interested in hearing about it. I don't like the interference associated with 90 degree XM connector on the 496.

Guys, Mouser has solderable Mini-USB-B plugs. I would just take a piece of Cat5 cable and make your own cable with these plugs. Part # is 806-KMBX-BPKITST30. USB cables have five pins but only four are used. I suspect Garmin is using the #4 pin for something else. Pins 2&3 are data, 1 is +5V and 5 is GND. #4 is normally not used.
Regards,
