hey guys, im purchasing my first nav unit on kijiji, and i will be meeting this stranger at a local mcdonalds. We agreed for me to install the unit before I give him the money. I'm only going to hook up power and ground to quickly power it up to see if it works.

Will I be able to see if the unit has a password as soon as I power it up?

Yes.

like Vblue42 said yes you can see the password option when you power it up when ever the power to the car has been cut like discounted battery elts say and then plugged back in or rmeoved from a car and put in another its kind of like a gm theft lock thing almost where it will propt you for the password

if it askes for a password and the guy selling it to you does not have the password good chance its stolen

if it does not prompt you for a password

really there is no way to see if it has been stolen or not

because i know i don't enter a password because i would probably forget it and im not spending major cash to send a unit in to have pioneer unlock it

An x940bt only came on market very recently... I would be asking for a location of purchase and a reciept / proof of purchase. If the seller can't tell you where he got it from and prove it I'd treat it as stolen and not buy it.
