I too did not have the appropriate keys, and I tried with the credit card strips to no avail (I could feel the release clip, but it did not release enough). I ended up finding an easier way to take the Symphony unit out - wish I had known this from the start! Remove the two vertical plastic strips that are on either side of the radio and object compartment. You need something thin and robust to act as a lever on their side to pull them out - they'll just pop out, be careful though not to use a knife or something like that, you'll end up denting the dashboard plastic. Once they're out, you'll notice three square holes where the clips of the plastic strips go. The top square holes are exactly at the level of the clips blocking the radio. If you shine a light in you can seen the metal clip actually. Now, you will need a piece of metal in the shape of an L - I took the L-shaped keys coming with IKEA furniture. I knew someday those would come in handy! Insert the short arm of the L in the hole, with the tip facing inwards, and use it as a lever to push the clip into the radio. You can do it on one side first, give a little tug to the radio (I used the volume knob), then do it on the other side and it will just come out effortlessly. Unplug the cables on the back and put the stereo aside, you can then put the plastic strips back and you're ready for installing the new HU.
