Apple CarPlay GPS wrong location issue

For CarPlay wireless you need, WiFi connected and Bluetooth connected. Try resetting both of these. When resetting Bluetooth, delete your phone from the head unit and your head unit from the phone...and create a new connection. This is an apple issue since they fully control CarPlay software from both the phone and the head unit.

Each legitimate MFG (Alpine, Kenwood, Sony, JVC, Pioneer) must go thru a through certification from Apple on each model...EACH model. It takes weeks..sometimes months to get final approval. Apple controls the software on both the Head Unit and the Phone side of the equation. Once Bluetooth connection is interrupted for any reason...even only for a second. Both the Head unit and the phone are out of sync. Therefore the connections must be fully reset. Rest assured, Apple is in 100% control of the software for CarPlay

This doesn't actually have anything to do with the CarPlay software on either the phone or the head unit. It has to do with the firmware that controls the GPS receiver in the car. THAT is where the problem lies.

It is 100% NOT an Apple problem.

I asked the dealer to update the radio system (Jeep UConnect) to the newest version and the problem seems to have solved. The dealer may tell you there is no update though. I went back and forth between Jeep Customer Service and the dealer three times. The dealer knows nothing and keeps pushing me to contact Apple.

I has this exact same issue with CarPlay on an aftermarket head unit (Alpine) in my 2014 Cadillac CTS. It was so bad I finally sold the car. What you are describing though, plus constantly trying to reroute, is precisely what I experienced. I went so far as to open a ticket with Apple. However they wanted to do a screen recording of the issue. Unfortunately that isn’t possible when connected to CarPlay.

Wired means the speed/GPS information data from the head unit is optional but recommended.

The fact that the location would go wrong as soon as the cable was connected shows the head end was providing the (incorrect) data.

Thanks @KiltenTime for the response, do you know if anyone has got this problem fixed? If yes, what diagnosis can I try. I had the base variant of the VW Polo, installed the infotainment system from showroom only.

Thats the issue...

Showroom guys have not connected CAN bus wire to head units. You don't need to set time manually, Head unit sync time and temperature using CAN bus.

CAR play and Head units needs VSS ( vehicle speed signal) to work correctly. VSS signal comes from BCM thru CAN bus wire. Ask showroom guys to connect CAN bus wire and scan full CAR, make sure error reported.

BTW how much did you pay ?

Thanks for such detailed reply. I did not pay anything as it was provided as complimentary accessory. My email id is iamspr91 at gmail. Could you please share your details over the email so that I can connect with you as looks like you can be great help in getting this issue resolved. Thanks for helping here brother.

Hi, everyone. I just started experiencing similar issues. I have an iPhone Xs Max, running iOS 12.4. I drive a 2018 Genesis G80. I have never had any issues using CarPlay. NEVER.

At least, unti last week. Coincidentally, last week I updated my car's navigation software (from MapNSoft) to the latest version, which was 13.5 for Hyundai/Genesis vehicles. Updating the software not only updates the maps for the in-dash navi, but it also updates the entire infotainment system, including Apple CarPlay functions. Ever since that update, Apple CarPlay has trouble tracking my vehicle. If I'm navigating somewhere with directions, it works pretty well, except when I drive into a tunnel, or through a long underpass. Then it loses me until I come out the other side. But if I drive without a specific destination programmed, the maps don't seem to know where I am.

To test this, I went into my friend's Hyundai, which uses an older infotainment build. I plugged my phone in, and it worked PERFECTLY. Then we went to my car, and had issues again. We even plugged my friend's iPhone into my car, and he had the same issues. So it's definitely not our phones. Considering that this all began after updating my car's head unit, it has to be the car. Although oddly, the issues are sporadic. Sometimes it's perfect. Sometimes it's hit or miss. Sometimes it's horrible.

Note: Outside of my CarPlay navigational issues, my car's in-dash navi works perfectly. So I don't believe it's my car's GPS antenna or anything of the sort.

Sounds like the firmware update to the car is expecting data more frequently from the phone now. Being in a tunnel, the phone likely doesn’t have anything to send. There are significant changes to CarPlay in iOS13. I wonder if that is related to some change made to the car system firmware. Maybe install the iOS13 beta now or wait until it’s released in the falll and see if that resolves it.

Try using android phone, they have better gps signal reception and resolved the same problem for me. The android navigation works perfectly in my car, even though whenever I plug iPhone the problem still persists.

You misunderstand how CarPlay typically works; whenever possible the car provides GPS data to the phone which displays the maps on the car screen.

It sounds like when the newer software causes the car to lose its location, it's reporting nonsense to the phone.

I bought a 2019 Jeep Cheeroke in Florida and moved to Georgia. I used CarPlay in Florida with no issue. As soon as I leave the state and plug in my CarPlay it still thinks I’m coming from Florida location. I even tried with an Android device in my car and it did the same thing. I downloaded iOS beta 13 and the issue cleared itself up. I had to go back to original iOS 12.4 cause it was draining my Apple watch battery terrible. Once back to iOS 12.4 battery watch last 2 days and gps is back acting funny.

I am experiencing the same problem with Apple Carplay on my Honda Accord. Apple Maps, Waze, and google maps all lose the position of my car while navigating. The Honda GPS system does as well. It may be in fact the antenna. Very frustrating!!
