I recently sold a 2011 430N RHB without the antitheft on the bezel to a guy on eBay. He emailed me today and says the unit is asking for a security code. I purchased the unit from another guy back in 2016 for my JK and was specifically told it would not need a code because it does not say antitheft on the front. When I received it, it was plug and play no code needed. Anyone ever heard of a non antitheft unit needing a code, this is really confusing me. Thanks for the help in advance!
