I try to replace my rear view mirror with a "new" one I bought on ebay. The issue is that if I replace it, and hook up the new one, my alarm goes off, central locking does not work anymore.
An engineer infomed me I need to do a software upgrade/adjustment??
We own a 2004 XC 70 Volvo AWD. The interior rear view mirror decided to die. There is a discolored patch (bubble type) in the middle section of the mirror. A new one will set us back a cool grand! Does anyone out there know how to fix it?
Volvo dealer says:
It cannot be replaced with a used one.
It's software operated.
A similar one from a similar car will not work, It will play havoc with other components, ie: sun roof, electric windows, etc.
All I needed was a new battery. They installed a new one, and I think that's waht caused the rear view mirror to go bad. They probably shorted the system as they were installing the battery.

Replacing the rear view mirror on a Ford Explorer is easy. The only obstacle you might encounter is fear of
breaking the glued metal plate off the windshield. Do not sweat it. You
can buy glues at the auto parts store to reattach the mirror to the
windshield (Difficulty: Moderately Easy).
Tap gently at the base of the mirror where it slides on over
the metal plate glued to the windshield and pull upward. Some rear view
mirrors have a small Allen screw that tightens the base of the rear view
mirror to the metal plate. Disconnect the electrical plugs if your rear
view mirror has them.
Pull the rear view mirror clear of the metal plate. Clean
around the metal plate glued to the windshield. If the metal plate has
come off because of harsh weather or from hammering too hard at it,
reattach it with glue designed for this job.
Clean the area where you will be attaching the metal plate on
the windshield. Apply the glue evenly on the surface of the metal plate
that will go against the window. Be sure to clean and scrape off all
the old glue before applying the new glue. Gently push the metal plate
against the windshield in the spot you wanted it and hold tight for five
Wait a day before putting the base of the mirror or
replacement rear view mirror onto the metal plate. Do not force the base
over the plate. Forcing it will likely dislodge it again. Press firmly
until it will not slide along the grooves of the metal plate. Reconnect
your electrical plugs and tighten the Allen screw if your new mirror has
one. Adjust the mirror according to your safe viewing preference
Hope help with this (remember rated this help). Good luck.
