I think I would uninstall car off phone and phone off car uninstall Android auto re connect everything again.

Maybe the update has not saved something, this is why I never update things apart from anti virus, if its working leave it alone.

 

Usually the problem is with the updates. I had a problem like that

 

Could be trying to tell you your phone too old. I had similar problem. On 69plate Vitara Bosch system wouldn't even load Android Auto. On 22plate Vitara with Pioneer work for while but eventually warning came up phone too old.

 

My 6 year old samsung worked intermittently with android auto.
I tried a new cable and it still worked when it wanted.
Six months ago I got an S22, no problems at all, everything works very smoothly.

 

This confused the hell out of me the first few times I encountered it with Apple CarPlay. The answer turns out to be pretty simple as it happens - assuming you are connecting with a proper quality USB cable.

When you use the phone mirroring via USB cable, the infotainment system disconnects the Bluetooth connection to your phone (which will be indicated in the upper right quadrant of the infotainment Home Screen) as soon as you plug in BUT it will not connect the iPhone (in my case) which will be indicated in the lower right quadrant UNTIL the phone is unlocked.

So the simple solution is to unlock the phone before you plug in to avoid the conflicting messages. If you don’t, it makes no difference (on iPhone anyway) as you can just unlock the phone after you plug in but you’ll obviously see the no phone connected message.

 

same issue with a OnePlus 7 Pro + Iphone 12 on a Vitara 2022 model year. On my car it works for 1 week, then out of a sudden it won't work. and like you, I tried almost everything and no result.
using original cables that came in the box for each phone.

what I found to work: go into settings reset to factory settings. and after that it works perfectly for a while. I had the cars for 21 days,3000 km so this happened twice so far.

 

Go to Suzuki Web site. There is a list of acceptable mobile phones that operate with the FACTORY fitted units. Could be that your infotain unit not compatible. I have the Pioneer that was briefly fitted due to lack of Bosch units. Suzuki GB have gone back to Bosch but they can have firmware problems. Despite software update to Pioneer rear camera stuck on when driving forward, shutting down etc. Dealer has reinstalled software again to see if that sorts it. Still watching it.

 

2024 Vitara SZ5: I have had problems - Android Auto, but finally (I hope) solved. There are a number of potential problems that cause disconnection or failure to connect. I purchased a short (less than 30 cm) USB 3 compatable cable. I unpaired bluetooth (do not re pair) - the cable will give you full phone functionality. Logic... It's all about Data speed. My phone is perhaps too slow to communicate via both bluetooth and cable at the same time. A short high quality cable will maximise data through put.

 

Hi I am having the same problem with a suzuki vitata 23 plate.it connected when I went over a pot hole even though for the past 20 miles it failed to connect so just left it.then it worked fine for the rest of the 100 mile journey.but today we went on a 40 mile journey and didn't work at all.such a pain.apperently there is no aftermarket systems I can have.they say its something to do with back of usb and back of head unit

 

it connected when I went over a pot hole

This does suggest the problem is with the cable and connectors from the back of the USB socket and the infotainment unit. There have been a number of threads on the forum about it. It seems the factory-fitted components were poor quality.
