Clock losing time

[WagzDad]

Real question: does it automatically correct if the altitude and location coordinates turn on? I think 90’ ASL is the trigger for functionality.

I honestly don't get it? Why does it loose minutes/month? How does that work? I don't own any other device that looses DIGITAL time!

The UConnect3 5" system does not have a cellular radio. So it can never get 'over-the-air' time corrections regardless of any settings.

Furthermore, this infotainment radio is about as lame and cheap as anyone could have installed in any vehicle made anywhere on the planet. FCA should be absolutely embarrased!

The clock circuiry looks like it's about as terribly designed as any high-school student would throw together from as cheap of a do-it-yourself kit as possible. It looks like there is no phase-lock-loop (PLL) drift protection, temperature compensation, or even an accurate quartz crystal.

My hunch is that the Chinese (or Mexican) supply chain had a plethora of low quality, low speed crystals (rejects) that were intentionally used to thrift savings out of this radio's overall cost. Instead of using crystals which are cut that electrically excite at the precise frequency to oscillate at a rate that is some pure numeric divisor of a second, why not install something else? Perfect crystals are in high demand so therefore are rather expensive. If you poor schmucks who can't afford the premium high end (high profit margin) option radio, then you need to live with what you get.

They know damn well that EVERY UConnect3 radio sold will have this problem. Worse, they also know there will never be a fix possible other than an upgrade to a UConnect4 or some other after-market swap out to a third-party replacement. Even more terrible yet, they also know that the upgrade will require a different HVAC panel on the dash. An HVAC that explicitly provides both volume and tuning knobs since the upgraded radios with larger screens consumed the UConnect3's dash's real estate.

Nope, if you are unlucky enough to have purchased any FCA vehicle (Jeep or otherwise) with a UConnect3 radio, you'll permanently have to live with lost time. Give up trying, resistance is not only futile it is totally and completely irrelevant. It's way more than a Jeep thing. It's an FCA corporate blunder of the highest possible magnitude. All in the pursuit of saving some number of pesos or yuans per vehicle.

Now if your willing to pay the couple thousand dollar upgrade just to have accurate time then mission accomplished for the company bean-counters. Their exorbitant bonuses are more than justified for that substantially increased profit margin. This suspiciously looks like it was a designed in slush fund...

Look us base model guys we like things manual and not electronic in our Jeeps. There's actually a little key that's supposed to come with the Jeep tool kit that you use to wind it up again every couple weeks. Mine was missing so I just use the one for the grandfather clock in the dining room. Hope that helps everyone I feel like an idiot now for not realizing

The TSB's in the attached link may help those with the clock issue (lose 6 sec / day). We were just given these for the 7in screen flickering when using carplay/android auto. Hope it helps.
