Vehicle Data can be obtained from the vehicles computer by closing door, selecting key to first position,& pushing phone answer & OK button together.
Then choose Vehicle Data & the vehicle amps & volts are displayed, This could possibly be useful if one is experiencing electrical problems.By scrolling down the list Vin & Engine numbers are also displayed. There are some information here that I do not understand. I would be grateful of enlightenment. Carsy.

I hope they atleast give us this keyless option.

Does anyone know if there is a way to lower the volume of the beep-beep when locking/unlocking doors?

Press Hang up telephone (red button), # and 1 on your center command hold them all untill the hidden engineering service menu appears.
Work for both MM & non MM.
Dont try SW update, it will look for CD and system hang for a while until you can select abort.
Try at your own risk !!!!!

And now that I can view this menu, what exactly will I do with it?
