Hello fellow Challenger fans!

I'm seriously looking to get the Challenger, and the SE has nice gas mileage and reasonable pricing. However, I've run into several conflicting option listings for the car on the Dodge site in addition to several others. Options of particular interest are:

Compass
Outside temperature
Tire pressure monitoring
Oil change indicator

There seems to be a difference between:
Tire Pressure Monitoring Warning Lamp
Tire Pressure Monitoring Display

My assumption is the first only tells you if the pressure is low but doesn't specify where, and the second tells you the pressure of all four tires and which one is getting low

I'm also confused as to the difference between:
Electronic Vehicle Information Center
Electronics Convenience Group

From what I've gotten off the Dodge site is the ECG contains the EVIC, but I'm not sure if one or both have the compass, outside temperature, oil change warning (GM calls this the Oil Life Monitoring System) and tire pressure monitoring.

Any help with clearing up what options above are available on the SE would be most appreciated!
