I recently purchased two Datasystem override kits for the 3GS. When I placed the order, I said one kit would be for an '07 and the other for an '09. I wasn't sure if there was a difference, so I thought I'd be specific.

I received the kits and each came in a box with different markings. Other than the aesthetic differences in the packaging, the labels and serial numbers from each box were different too:
1. TTN-46, 2921643
2. TTN-46Y, 2589646

I have not heard back from JZSINTERNATIONAL JAPAN to know which kit is for which GS.

Does anyone know if the override kits are different for an '07 vs '09 or which one is for which year GS?

Thanks

 

Datasystem said TTN46 & TTN46Y are the exact same kits. The TTN46Y is a limited package design. Hope this helps someone in the future.
