I did not took into the dealership to activate the AUX switches.
The JSCAN app was able to activate it - After a few hours the AUX switch option was available on the Uconnect
I will be dropping off my JT at my local dealer. I referred them to the TSB and mentioned that the steering just feels way too loosie at highway speeds and needs constant correction to keep it straight. Will see what they say.
Please file a Vehicle Safety Complaint at NHTSA to raise awareness...
I got 35s on my overland. A bit more sluggish, but its fine for city and hwy driving. MPGs took a hit, averaging 16-17. 8th gear is not used as much as other mentioned.
It handles just fine.
JSCAN to adjust all tire settings
I bought the Jscan - about $90 all in.
I adjusted the tire size and my speedometer is in synch. I also adjusted the TPMS since I am at 32-33 psi for normal driving.
Other settings can be changed too with it.
