There are screws that are visible from underneath the pods that need to be removed but then you will need to open the trunk and remove the entire inner trunk liner with all it's screws to access the other screws that need to be removed as well. After that they will pop out.
The pods do come off pretty easy and my installation went pretty simple. I was in a hurry thou so those simple mistakes are made. If it seems not to be going well, just stop for a drink and go back to it.
