I sold quite a few NIST1 based on the compatibility shown in document 12661 and according to that document, the RF kit/remote start is optional - so we sold them as 'stand alones'.
We had several problems with customers whose EVOs did not pick up 3x lock and later saw document 12651 which has the same exact list of compatible vehicles. but says that the remote start IS needed.
Which document is correct?
I have a customer with a 2009 FX50. It is listed on both installation documents. 12651 says he needs the NIST1 AND a remote start.....12551 says he only needs the NIST1.
Please clarify
