Got the wiring info, just wanted to double check the modules I need for a security/remote start system are DEI 456G and 555L.  Correct?

Anyone know anything about installing a stereo in one too?  Does the stock HU have to be relocated?  Is the stereo amplifier in the HU or is it external?

Thanks.
