HOW-TO: RS3200 finding and adjusting the GBS sensitivity

[Gilley]

This is for those of you who purchase the RS3200 upgrade kit and want to adjust the GBS sensitivity.

With the heater duct out of the way, look under the dash to above the steering column, about where the heater duct should go. Find a bracket with two boxes bolted to it.

Look for this box

Unbolt the black box and 1) either disconnect the three harness connections and remove the box entirely, or 2) disconnect the large white connector on the end and move the box around. Pic here

This is what the back of the GBS looks like.

Connectors of the box and the rotary sensitivity switch

Note the rotary dial on the right. Mine was factory set at four. Going to a higher number increases sensitivity. I set mine at 6 which allows the unit to detect tapping on the passenger side glass, but hopefully won't sound the alarm if acorns hit the glass.

Rotary switch

I found it easiest to simply unplug the large white connector and move the box around while adjusting the sensitivity.

Reinstall the box and you are set to go.
