I didnt have anyluck with out an adapter - I used this one from metra and it hooked up to the can-bus no issues. I didnt want to spend the extra but n the end it made it so much easier.
METRA
New to the Jeep family - just traded in a Honda Civic for an 2018 JK Altitude in Bright White.
So far I have become one with the interior as I have adding new speakers an amp and sub woofers.
At some point I would like to switch to 17" tires as the altitude came with 18 x 7.5's.
