How can I check the software version currently installed on my GXM 40 XM antenna and how can I update it? Also, what is the current software version. Last question, will the GXM 40 antenna loose its signal due to vibration of the antenna? Thanks!

The GXM 40 software is automatically updated by the unit to which it is attached, so you never have to worry about this.
We don't expect normal vibration to affect signal reception, but there are limits to everything.
If you shoot us an email at [email protected] we can discuss details of your installation including which portable GPS you are using and whether or not your unit has the latest software.
