Bob, I picked up my Overland with the Tech group just a few days ago also. Like you I found all the systems work very well. The only one I am confused about the the front collision warning.
Is that something that only works when the cruise is on or should it be working all the time? It's pretty hard to see if it's working but I have purposely came up pretty fast on the rear of a car in front of me but never got a warning.
Any thoughts?
Thanks
I haven't tried to figure it out YET. Here's the info in the owners manual for the collision warning.

Forward Collision Warning — If Equipped
Forward Collision Warning (FCW) warns the driver of a potential collision with the vehicle in front of you and prompts the driver to take action in order to avoid the collision.
FCW monitors the information from the forward looking sensor as well as the Electronic Brake Controller (EBC), wheel speed sensors, i.e., to calculate a probable rear-end collision. When the system determines that a rear-end collision is probable a warning message (both audible and visual) will be displayed on the EVIC. When the system determines a collision with the vehicle in front of you is no longer probable, the warning message will be deactivated.
FCW Message
Warning!Forward Collision Warning (FCW) is not intended to avoid a collision on its own. The driver has the responsibility to avoid a collision by controlling the vehicle via braking and steering. Failure to follow this warning could lead to serious injury or death.

Changing FCW status
The FCW feature can be set to far, set to near or turned off in the Electronic Vehicle Information Center (EVIC) refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information. The FCW Status Off, Near or Far will be displayed in the EVIC.

Example Only
The default status of FCW is the “Far” setting, this allows the system to warn you of a possible collision with the vehicle in front of you when you are farther away. This gives you the most reaction time.
Changing the FCW status to the “Near” setting, allows the system to warn you of a possible collision with the vehicle in front of you when you are much closer. This setting provides less reaction time than the “Far” setting, which allows for a more dynamic driving experience.
Changing the FCW status to “Off” prevents the system from warning you of a possible collision with the vehicle in front of you.
Note: In the “Off” setting FCW OFF will be displayed in the EVIC. <A name="">
FCW Off Example
Note:
- The system will retain the last setting selected by the driver after ignition shut down.
- FCW will not react to irrelevant objects such as overhead objects, ground reflections, objects not in the path of the car, stationary objects that are far away, oncoming traffic, or leading vehicles with the same or higher rate of speed.
- FCW will be disabled like ACC below with the unavailable screens.

FCW Unavailable Warning
If the system turns off, and the EVIC displays “ACC/FCW Unavailable, Vehicle System Error”, there may be a temporary malfunction that limits FCW functionality. Although the vehicle is still drivable under normal conditions, FCW will be temporarily unavailable. If this occurs, try activating FCW again later, following a key cycle. If the problem persists, see your authorized dealer.

Service FCW Warning
If the system turns off, and the EVIC displays “ACC/FCW Unavailable Service Radar Sensor”, it indicates there is an internal system fault. Although the vehicle is still drivable under normal conditions, have the system checked by an authorized dealer.
