I’ve already loosened the screws at the top and still nothing

I think the first 2-3 minutes of this one will show how to remove the fasteners from the bottom up...

When you loosen the screws you are not meant to take them out, you only need them up enough to disengage the locking mechanism that the screws are connected to , once loose you push down on the screws which will disengage the mechanism holding the radio in.

This also helps when refitting the radio as the screws are a little bit difficult to get back in without dropping them into the dash, so make sure you get them back into the thread of the mechanism.
