Removing hazard/clock from head unit!

Im swapping my non clock hazard for one with a clock. I have the radio head unit out already, but for the life of me cannot get that hazard piece out. There are 6 plastic tabs I need to push in but it isn't working. Just seeing if I'm doing something wrong.. Please help if you've done this!

 

I used multiple butter knives from the old ladies silverware drawer and just popped it out.

 

Willing to see the non clock hazard unit? Been trying to find one to replace mine since I have a after market radio with a clock so I'm reading two clocks haha
