I've tried both Android Auto (Razr+) and CarPlay (iPhone 13) on my 2023 M340i. The resolution using CarPlay appears much sharper than Android Auto.

I've tried increasing the resolution in the Android Auto developer settings, but it looks the same.

Does anyone else have this experience?

It's linked to 5Ghz Wifi. Is your BMW and Phone connected over 5Ghz network? You can check using WIFIman app

Yes confirmed 5 ghz with WiFi man

Did you find a solution for increasing sharpness/resolution of Android auto ?

No unfortunately not. I'm still interested in finding a solution.

I didn't know this was a thing - I have the S23 Ultra. I've always thought AA looked great on my ID7 display. I can connect my work iPhone to do a comparison.

This is only a guess from me, but I think it might look fine on <iDrive 8 because the screen on ID8 is now 2880*1080 pixels. I don't think Android Auto can scale up to this resolution cleanly.

Try tweaking the 5GHZ parameters by coding, below is the parameters that works perfectly for me with no drop-outs, but read the comments since my case is very special: I have no WIFI antenna because my MGU units is missing the WLAN port, and didn't came with Android Auto and Carplay, or Wifi capabilities from factory :

- WLAN_2G_TX_POWER = 20 (was "14" = this control the transmitter power by increasing it, you increase the transmition range but can result in interferences and drop out, I increased it because I don't have an antenna port in my MGU unit and I used to lose signal as soon as I move my phone from the headunit)

- WLAN_5GHZ_CHANNEL = 36 (was "nicht_aktiv" meaning that 5Ghz capabilities wasn't active in my headunit, reason why resolution was very limited. This is the channel to be used for 5Ghz, i used 36 because it seems less crowded (based on Wifi analysis on my daily commute) and helps avoid interferences that leads to drop out, otherwise you can make it automatic selection, by chosing UNII3 Auto if that works for you)

- WLAN_5GHZ_CHANNEL_WIDTH = 20 (was "80", I reduced it to boost signal and have tighter channel to avoid overlap/interferences with other channels)

- WLAN_5G_TX_POWER = 20 (was "14" same explanation as 2G_TX_POWER above but for 5Ghz band)

- WLAN_CHANNEL = 11 (no change)

- WLAN_DIAGNOSE = aktiv (no change)

- WLAN_DOMAIN = us (was "de" meaning Deutschland to comply with authorized WIFI channels in European market but my phone is a US smartphone and I'm leaving in Morocco. Also i was looking on some Russian forums they advised to change to US to support more channels/band)

- WLAN_WIFI_MODE = ap+go(was "ap", it was recommended in Russian forums but don't remember the explanation)

In addition to that, make sure that in Android Auto developper setting, the Video Resolution is set to "Allow up to 1920x1080".

I hope it helps!

Thanks! The issue for me at least is not connection drop out, just sub-par resolution (compared to carplay). Interesting enough, I have a 2025 X7 and when I go to iDrive (8.5) homescreen with Android Auto running navigation through Google map, Google map shows on the right section of iDrive homescreen and the resolution is perfectly fine. Also I thought coding is not possible via bimmer code because the new iDrive has some cloud validation or something for coding.

My experience is with iDrive 7. Sorry I can't help further with iDrive 8 or later.
