just bought an astra with a multi purpose display just above the radio .
this displays radio channel etc. but also in car temp etc.
also just bought cd radio to fit in the car.
oh dear! (and other words)
1/ can i replace the original radio cassete without disabling the
temperature/clock etc.?

2/ if i can, how do i get the radio out seeing as the correct special tools
don't seem to be unlocking/grabbing the unit.

any gems of helpful (i.e. no mickey taking please) wisdom will be very
gratefully received as both the car and the new cd/radio were a present for
my wife, and she'd be most unpleased if the radio had to go in my old
banger.....

thanks in advance
