to take it out completely if u can't get the key to work
1)remove the plastic trim around the front of it----it clips in and 2 screws.
2)unplug the switches---dont forget to wire them back up when reinstalling...they can only fit one way, so dont worry
3)unscrew the 4 screws which hold the brackets holding the stereo
4) unscrew old stereo
5) replace with new stereo and wire up correctly
6) reverse process
I had a quick go at sticking my hand round and trying to push it out last night, i completely missed the stereo and out popped two cup holders! Didn't even know i had any till then!!!
you will also relaise that its hard to use those cup hodlers if driving "spiritedly"----your hands MAY hit the cup and spill some drink
but if parked, ,,,they work well...lol
glad u got the deck sorted
