Good luck in getting the tuner box. The part you need is IN1460. I have tried with a couple of dealers in my area. One finally called me back and said the part was 355.00 another car installer told me the part was 178.00 but could not get it anytime soon. Then i contacted a guy in colorado who said he could get it for 169.00 (which is a big difference from 355.00)but when i told him i was in ky he backed out. Called invision but they would not sell me the part. I Think i should just switch to another brand. Save me the time and headache
