Swap Rav4 and celica headunits how hard?

[Kit99bar]

I want to put my cassette and CD player from my celica into my gf's Rav4. Is this a pretty easy swap?

any guesses and advice from people who've done somethign similiar?

Is it the same HU size? I know that Toyota used the same HU in most of it's cars. (camry, corolla, celica, highlander, 4runner) I have never been in a Rav4 so I'm not sure what it has. If it fits in the opening I'm sure that you'll be able to find mounting points for it. The HU is pretty genaric so it fits in a lot of cars. Other than that you may need a wiring harness? If you aren't using your old one cut it and hard-wire into the Rav4 system. I'm not sure of the power output of the 'premium' Celica's HU w/o the amp. Maybe toyota has a harness that plugs into the HU and the rest of the Rav4 system?
