I tried to get Srt Performance Pages in 2018 chrysler 300s.
But it shows warning that it has invalid ISO. And nothing works for the car. Any help?

I have a 2018 300c and I had to get a bypass and connect the ELM 327 through the trunk. The HUGE problem is the logo SRT is the only thing that is new on my uconnect screen. I'm also waiting for HELP.

Obd2 Cable for FCA 12 8 Gateway... https://www.amazon.ca/dp/B0C1YGJ96S?ref=ppx_pop_mob_ap_share
You need to get this tool and connect it under the steering wheel not in obd port

See this video for reference you’ll get SRT logo and Srt font in speedometer. Add performance pages and reset uconnect by holding power and tune button you’ll get pages in odometer and uconnect screen

Thank you for the information, but I did everything that you stated multiple times even. The performance pages are still not present.
