Henry - from an old Magnadyne thread, per JAMiller45 (FR Engineer):
"Chevy and Ford, the radio will come out with the removal tools. Solera is attached to the plastic housing, so you need to remove the front panel, and then remove the screws(TORK) to take out the radio."
From one of my posts in the same thread:
"The removal tools that came with the unit don't work on the Solera installation, as far as I can tell. I pried/pulled off the simulated wood trim (snaps in), disconnected the connector to that piece (emergency flashers, etc), removed the screws for the radio and the climate controls (torqs type), jiggled the unit (radio plus climate controls) out from under the two screw connectors for the dash tray, and pulled it all out."

Good Luck -
