Hello, I'm a 2IS owner, but I'm planning on trying to get radar cruise control on my car. I've noticed that the GS from 06-07 seems to have the same looking radar sensor, with the same 5 pin layout, albeit with a different part number compared to the IS. The radar cruise control option on the 2IS is so rare that its basically impossible to find parts, so I am turning to you guys, to see if my hunch has any worth. Is it possible for the radar sensor from the 3GS to work on the 2IS? Is there any chance it could be compatible?
