You mentioned you went from the 7-inch Uconnect radio and upgraded to an 8.4 premium radio did you keep the OEM and you did this yourself I heard this was extremely difficult@TheDreamcatcherJL:
No re-gear. Running stock. May change wheels and go with 33s down the road. Haven't driven much in 2020 due to COVID, so I barely have 4,000 miles on my JLU (purchased in Feb. 2020). I'd like to get some more mileage out of the stock wheels and tires for now. Also, I have a Sport Altitude and like the stock black 18" wheels.
To keep the thread on track, I used JSCAN back when I had my '15 JKU to enable DRLs and a couple of other things. So far, I've used JSCAN on my '20 JLU to disable fog light drop-out and enable Off Road Pages in my new 8.4" radio (upgraded from the 7").
