The good news is the oddment tray just unclips on either side at the back.
The bad news is ....
it's a cavalier .. it can only be done (afaik non-destructively) by removing the radio/oddment tray first. First unscrew the centre console, unclip the gearstick gaitor, slide it back. Pull out ashtray assembly. Remove the screws , 2 each side of footwell , & 2 screws where ashtray's been. pull that bit back, you'll notice the lower tray mounts are
behind this. ( may need a little bit of flexing to get this bit in/out when you eventually get to that part)
Now for the top.( you're not gonna believe this!)
Unclip the trim from below the speedo cluster - bit of gentle force needed- and remove the clock. Remove screws for heater controls. On the top right one(s) you'll notice that again the mount you want off is behind the heater control ones. For me, this one took a lot of flexing to get off, and eventually back on. You should now be able to remove the radio/oddment tray, unclip the tray and reassemble.
Since you've gone this far you'd be as well to change the bulb in heater console. I used a flat-ended white led, doesn't dim but it'll probably outlast me...or the car...or both
(remember to check it before re-assembly, led's only work 1-way round)
Good time to change your gaitors if required too.
Just done all this 3 weeks ago, so think I've covered everything, hopefully clearly
