I used to sell Toyotas. Your not going to get an answer on bestbuy.com. The best way to solve this problem would be to actually walk into the store and talk to a person. Buy here is a little help. Almost all aftermarket cd players use a mounting kit. It is basically a piece of trim plastic that goes around the player. The corolla has a large cd player, and your going to need a mounting kit to install it, unless you get a double dim cd player which is a cd and cassette deck in one unit. As for the ipod jack, tons of popular models have these... try crutchfield.com they carry tons of audio equipment
