New radio for my 2002 Toyota Camry?

I bought a GTA Car Kit but had to return it because I didn't realize it wasn't compatible with my radio model. I really can't find any other option in getting a new radio for my car. I want to be able to use my iPhone and plug it into an AUX port. I'm not spending over $200. I was even looking at something that would replace the whole radio entirely like this SuperSonic screen/radio from Walmart.com.

I'm sick of using CDs and the cassette things don't work and I hate the radio transmitters because the sound quality sucks.

The only thing I feel like I'm left with is to buy a normal size car radio. Two things I don't like about this is the little "pocket" is leaves underneath and the fact that I had one stolen out of my old car. (Probably because I left the face plate on but still, someone will see that and know it's in my car somewhere.)

I have a 2002 Toyota Camry LE. I also have JBL speakers and I read somewhere that some things don't work with JBL speakers (or that I need some kind of $50 cord).So Please, Please, Please someone with car knowledge or car audio knowledge respond to this! I would really appreciate it! I need to know what my best option is. Do I buy something new or get stuck burning CDs until I get a new car in 5 years or so?

I don't know what you read but i highly doubt you need anything extra speakers are speakers, what you may have read is you need a crossover for JBL components but there would be no extra cord need to simply use jbl speakers instead of stock speakers, and just buy an indash kit for your vehichle and the stereo will work and fit.
