Default Force Wired Carplay

The problem, my Carplay cuts out on long rides. Long ride being 4 days, 2500 miles. This may be due to a wireless Carplay connection, which uses wifi. Due to the open nature of the motorcycle, this wireless connection is susceptible to interference that an in car connection would not be. Is there a way to force carplay into wired mode? If I direct connect my iPhone to the USB port in the covey, does that default to wired Carplay?

Longer version
I did a multi-day ride using the Maedhawk passthrough USB with my iPhone plugged in line. From what I understand, the Maedhawk only passes through power to the iPhone. There may be an updated version of the device in the near future that will pass data through as well. As it is, this puts Carplay into wireless mode, as there is no wired data connection for the phone. I tried a USB hub as well, to which I plugged the Maedhawk and the iPhone in to.. The Road Glide throws an error that "USB Hub not supported"

One option, use the under seat headset adapter option from Tim's Stereo Systems. I would then directly wire the iPhone to the in covey USB port. I believe I have seen reports that Carplay still loses connection in this scenario as well?

Yes, delete the IFCU from your CarPlay settings and delete the phone from your IFCU devices. Then when you connect the phone to the IFCU via a cable, it will ask if you want to use the IFCU for CarPlay (yes), then it will ask if you want to use Wireless CarPlay (no).

Well, there you go.. I wondered how that was done. I've been running wireless since I bought my bike Feb 2024. I though of going wired, but haven't really looked in to how to do it. I'm not keen on having to plug and unplug the phone every time I jump on and off the bike.

To the OP.. Wired CarPlay uses Bluetooth only. The WiFi connection is for the embedded Nav functions such as weather info as well as providing traffic and weather overlays on the map screen. It also provides the ability to automatically update the maps over the air. And... just recently we got the ability to do IFCU software updates over the air using the WiFi connection.

You are partially correct. Wireless Carplay uses the Bluetooth connection for the initial pairing setup, and then for the vehicle entertainment system to recognize the iPhone to connect to wireless carplay. Once the connection is established, wireless Carplay then uses a dedicated wifi connection to do the data transfer between the phone and the display. If you are experiencing disconnects with Wirless Carplay, it is highly likely an interference issue with this wifi signal. In a car, you have additional protection from signal interference. The motorcycle is out in the open, and more likely to have a problem. You can find this in the Apple documentation, or a simple Google search.

I am hoping that using wired carplay will eliminate these interference issues.

Interesting.. I guess some vehicles require the WiFi. (A Google search showed that).

But I've run wireless Carplay just fine with no WiFi.. When I got my bike I had an iPhone 7. The hotspot was only capable of providing a 2.4 GHz WiFi signal. The IFCU will only recognize a 5 GHz WiFi signal. When trying to set up WiFi, the bike didn't even know the phone's hotspot was there. I had nothing configured as a WiFi device. There was no WiFi icon on the IFCU display. But I was running wireless CarPlay just fine. ( I later upgraded to an iPhone 16 which I can use for a WiFi connection).

And.. For interference.. Yes. It can be a problem. There's a spot I go by on the way to my dealership where I always.. without fail.. get a CarPlay cutout. There's nothing in the area that sticks out, but it has to be interference.

That would explain why I couldn't have both WiFi and CP at the same time.

You may still have an occasional problem with wired if you lose cell service when listing to music (Sirius) but will come back when service is restored.

This video is from "In The Friction Zone" one of many that Tom does for information on our new bikes. You might have seen them before but if you didn't this one is quite relevant to the conversation. I use this same setup on my 2024 SG and it seems to work most of the time. I use the Cardo headset primarily and not the bikes speakers though.

The only way for Wireless CarPlay to function is via a wi-fi connection. Nothing will tell you this wifi connection is happening. Next time you have your phone connected via wireless carplay, turn your wifi off on your iphone and see what happens. It will tell you that the wireless carplay connection will terminate.

The iPhone 7 has a dual band wifi chip (2.4GHz and 5GHz), but the hotspot capability is limited to 2.4GHz.

This is completely unrelated to CarPlay functionality. CarPlay will not disconnect if you lose cell service.
