Where is my cd 'hide away unit' ?

Hello, can anyone help me locating the whereabouts of a Sony 'hide away unit' for my 98 2.5 DSE P38 cd changer? As a recent battery change has caused a need for pressing the reset button according to the user manual.

Either in the boot on one of the side panels, or under the front passenger seat accessed from the rear seats.

Brill, thanks, I thought it might have under the dash somewhere. But then thought surely not because it must be a regular occurrence. Just got to sort out the window error settings, which hopefully won't be too difficult.

do they need resetting? quick and easy if so

Whats up with the windows?
Are you getting the window not set message?
If so roll each window all the way down and keep holding the button for about 2 seconds then roll the window all the way up and hold the button for a second or 2 and you should get a beep with window set on the display
Do this for each window in turn and the sunroof

Ah, that's what I need to do then. I do like this Landyzone site, it's sorting all my problems out in no time!
Thanks very much, Gary
