iOS 12 Bluetooth Uconnect issue

I updated my iPhone 7 to iOS 12, and immediately noticed that there is now a significant lag in song selection when connected to bluetooth in my car's Uconnect head unit. When a new song plays, the song run time is frozen for exactly 30 seconds while the song plays. If I try to toggle next/last track selection using the car's audio controls during this time, nothing happens until the 30 seconds pass, then it changes to the next song. It happens very consistently now with every new song that plays. Also, during some songs it'll do this freeze for 30 seconds where song navigation won't trigger.

Can't overstate how annoying this is. Has anyone else experienced this?

This issue started for me after I upgraded Uconnect to 17.43.01 on my '15 Grand Cherokee on 10/2. I had iOS 12 on my phone already, and I did not have the delay before the Uconnect update. The delay in the radio controlling the phone usually was 30 seconds, but sometimes would be better. There was no change in behavior with the 12.0.1 iOS update.

I did a hard reset of the phone today (vol up, vol down, then hold the power button), and now the issue is almost gone. I did have one instance of a delay at the beginning of the pairing, but it went away after a song or two. It's possible that a hard reset (not a power off) will help some of you.

It will be interesting to see what iOS 12.1 will bring.

For everyone with issues - could you list your vehicle make, model and year? I know that FCA changed their head units between model years. Might be some commonalities. Mine:

2016 Dodge Charger Scat Pack, 8.4N Uconnect w/Nav

It's almost-certainly an iOS 12 change issue... as my iPhones NEVER had a problem in my Pacifica... and my iPhone 8-Plus that I updated to iOS 12 (before trading it in) started having these issues, and my brand-new XS Max shows no difference. Exact same issues. iOS 12 seems to be the common denominator, so far.

Mine looked to improve but ultimately is still the same. On my one hour drive back home, it worked flawlessly for 45 min. Then when I shut the car off, got my kids from day care and got back in, the screen and track freezing came back with a vengeance for my 15 min back home.

This morning, my SXM was stuck in "XM is updating, please wait" mode all morning - I thought perhaps Uconnect may have pushed something down via AOTA. But ultimately I'm still experiencing the issue.

Just got this from Jeep Customer Assistance Center...

"Thank you for contacting the Jeep Customer Assistance Center.

I appreciate the time you have taken to contact Jeep in order to obtain further assistance with this concern. This is one that we are working toward correcting as soon as possible.

Apple dropped a new update recently, which was a bit of a surprise, as originally we were not expecting another update until January 2019.

Due to the surprise nature, we are finding some issues with the new update and customers may start to see issues with their Bluetooth connection to their vehicle as well as the use of the Uconnect app on their phone.

Thank you again for your email. Should you require additional assistance, or have any new information to provide, please reply to this email message or call 1-877-I-AM-JEEP (1-877-426-5337)."

Do you know if there are issues with units that have Apple Car Play? I cannot remember which year they introduced it, if it was '17 or '18. I assume it is a shot in the dark getting RAM to upgrade mine to one of those versions. That is if there is no issues. I don't even know if the screen would be the same, but the box would just be different.

I was curious, so I call Crutchfield to see what options there is. I figured it would be extremely expensive to get all the factory options to still work. I was worried about Climate Control, Backup Camera, XM, USB port, steering wheel controls, and Aux port. It is not cheap, but they did put a package together to keep all that and include Apple Car Play. It was around $700 for everything. I did not purchase it. There was other options but I would loose factory features. I am going to try and just plug my iPhone into the USB and see if that will work better for now. I may look at a new head unit down the road if Apple and Uconnect cannot get this fixed.

@BRMNTX, strangely this didn't work for me before but it worked flawlessly today. Interestingly as soon as I turn back to Media on the screen, the freezing occurs mid-song for 30 seconds. Going back to Phone or Climate allows for seamless track selection again. So, looks like it has to do specifically with how the tracks are displayed on the Media screen?

Brief update for anyone following this thread... I upgraded to a 2019 Charger Scat Pack with the latest UConnect head unit and my iPhone8 now works perfectly. Fast, responsive, no weird issues. Most of my experience has been wired through Carplay but I briefly confirmed that Bluetooth works too. So to solve the problem just buy a new car. 👌🤑

@Majorachre, congrats on the new car. Yea, every time I've BT'ed to the 2019 FCA vehicles in our work fleet, they've worked flawlessly. Looks like the issue is isolated to the older head units. Still having issues, and am tired of always having to hardline my phone and skipping BT. The Climate/Phone screen workaround no longer works for me, same freeze-ups there now.

I have also had this issue with my 2017 Ram Sport and Iphone 7. I have tried everything mentioned previously including a factory phone reset and Uconnect update with a USB stick (Canada). For the time being I can skip through songs immediately if I display the phone screen, this is hardly ideal. Coincidentally, we also have a 2015 Trailhawk with the same Uconnect head unit and it works flawlessly. Phone is currently iOS 12.1.3.

OK, I'm not reading through 9 pages to see if anyone has noticed this, but:

IT'S LIMITED TO APPLE MUSIC!

This DOES NOT happen with Amazon Music. Not at all. Skipping is fine, artwork update is almost instantaneous, everything.

Siri still sounds like crap, but that's the UConnect software. After all these years you would think Chrysler would have come up with a solution for all their customers with Apple devices, but why am I surprised? Chrysler has never cared about customers once they bought a product before, so I didn't expect them to start now. Ongoing support is not in their playbook. With the introduction of Android Auto and Apple Carplay in 2019 models you can be assured you will never see a resolution to this.

Ah gotcha. Yea, it seems to be isolated to the Apple music app, specific to native files and how track selection works in relation to on-screen displays.

I can tell you that there is no way to put Carplay/AA onto older HU's (anything older than '17) because the hardware is different. Others on this (long) thread have replaced their older head unit entirely with a newer one, but like you said, it costs $$$. This issue has been ongoing since iOS12 was released, back last September - 6 months or so. Not great.

I brought my car to the dealer/service center today and they say I need the radio replaced. I have a 2013 Dodge Dart. My issue is none of the bluetooth/hands free options work. I updated the uconnect software, but it didn’t help. I tried all the ways people have mentioned to kickstart it into working and none of them helped. I tried a friend android phone and it didn’t work either.

Yes iPhone XS here, iPhone 7 last year, same issues. Dodge will not update head units under warranty, it’s not a warrantable issue. They’ll point to Apple, justifiably so, while Apple will point to Uconnect, perhaps justifiably so.

I have an iPhone 8 with the latest update 12.3.1. I have a 2015 Grand Cherokee with Uconnect 8.4 w/Nav. I have the lagging issue just like everyone else but I also have an issue with my heating and cooling. With the AC on and set to 74 degs the AC is reading approx 60 degs at the vent via thermometer. When I move it to 76 with AC still on it will blow approx 110 degs. Dealership replaced the stereo unit twice and can't figure it out. I am just curious if this also is an IOS issue. The dealership said that all of the climate controls are run through the stereo. Thanks for any input
