i am going to replace my dess module and antenna this weekend, not ignition switch just antenna, i have a manual and read about the module learning procedure, but it is not clear to me if i can just change the antenna without any learning or re-set, it has a lot about changing the antenna along with the switch but i can't find anything about just the antenna, has anybody changed just the antenna that can tell me for sure? not just a guess but for sure, i will replace module first and make sure its a go before messing with the antenna.
