Just found this really useful link. I'm still not sure of the ashtray holder is the same part for my Coupe, but the installation should be the same.

Do not, I repeat, do NOT follow these "easy way" instructions unless you have tiny little girly hands!!!
I attempted the so called easy way and it is very problematic. It is impossible to "feel your way" on the back of the radio and re-install the 4 block connector. And the sharp edges of the exposed sheet metal under the dash will leave you wounded and bleeding. Save your self a lot of trouble and remove the vent (can be done with a simple flat head screw driver, no special tool required as mentioned in the easy way insructions) and the radio and the whole installation will take you no more than 20 minutes.
