2018 charger hellcat.....so i went to dodge & had my radio replaced due to faulty navigation. All works great except my IC coolant guage is not displaying any temp....it shows in the cluster but not on the srt page....anyone else have this issue?....thanks all
Try what Blickie suggested.
I had my 2018 Hellcat uConnect radio replaced back in July 2020 due to bad NAV system.
No issues after the new radio was installed. But I had issues before and not with just the NAV unit.
Long story short the issues appeared to arise from lack of sufficient use. The battery would run down -- would still start the engine ok but with a slightly longer crank time -- but at some point upon engine start the battery voltage would drop too much and this apparently would "glitch" the uConnect radio. While I never say any one particular gauge missing Performance Pages would refuse to load.
By using the car more often -- mainly for my 60 mile round trip work commute several times a week -- this kept the battery topped up and the uConnect radio worked without any signs of any issues.
