Well, actually it is correct. The '07 Camry actually has the system built-in basically, but out of the factory it works as a keyless entry only (unless you have an XLE which only needs the GBS feature).
That part number adds the RS3200+ system with GBS (or only GBS if you have an XLE), which gives you the abillity to activate full alarm features (door open alarm, GBS, passive arming, etc.). I know because I just purchased it and installed it myself for $88; however, I am currently having trouble getting a dealership to program it properly using the scan tool. The first dealership I took it to knew nothing about the system, charge me $20 to program, but then told me they couldn't get it program, but took my money anyhow. I'm trying a Lexus/Toyota dealership Monday that seemed to know more about the system. I will let you know how it goes. The install is pretty much cake, just interfaces with the factory wiring harnesses and mounts in a factory location behind the glove box. If you want to take a look at the instructions, just PM me and I will send you a copy.
