If it is the same as other toyotas, If you flip the airvents all the way up, or down, I forget, there should be screws in there. You remove the screws and the front panel pops off. You then unbolt the the radio from the sides,( toyota has been doing this for atleast 10 years). If you have a double din you may have to drill holes in the bracket to mount the radio. If you have a single din, you would either need a dash kit, or to make a plate to fit in the opening. Post a pic of your dash, and I may be able to help more.
