OTTOCAST U2-AIR Wireless CarPlay Adapter 2024 - Apple CarPlay Wireless Adapter Convert Wired to Wireless Plug & Play Dongle 5Ghz WiFi Auto Connect Online Update for iPhone & OEM Wired CarPlay Cars

For those beginning to use the OTTOCAST U2-AIR device, but the USB ports in your vehicle continue to supply power even after you turn off your car and walk away from it, please note that a company named Cable Matters makes a one-foot-long USB extension cord with a toggle switch (ON OFF). Just search for Cable Matters usb on off switch 1 ftThe particular extension cord I just mentioned is USB-A (male on one end, female on the other end, being an extension cord and all), so if your vehicle's ports are USB-A (the older type), you should do well with the Cable Matters cord I've suggested. On the other hand, if your vehicle's ports are USB-C, perhaps you can search for and find a similar on-off extension cord for USB-C. All of us USB-A people wish you luck.Use the switch to disconnect the U2-AIR immediately after turning off your vehicle, and to reconnect it after your head unit boots up for a new trip.The OTTOCAST U2-AIR is still very new to me, but not being able to turn it off without physically unplugging its USB cable was the only complaint I had, and I now consider that issue to be resolved (good enough, anyway) thanks to the Cable Matters on-off switch.I've noticed there is a longer delay when I press the steering wheel button to skip to the next song, but even when using wired CarPlay, I have always had a delay of maybe 1/3 to 1/2 of a second. Now it's closer to a full second. That's the trade-off: a couple of slight delays in exchange for keeping your iPhone in your pocket or purse. The delay is fine with me; I'm already used to it. Changing the volume is just as fast as it ever was. Touch-screen response is also the same as ever, imo.I'm pretty happy with this device so far, it has actually been making me smile as I drive. But I have read the other reviews and I will be watching and listening carefully to see if I experience any of the other mentioned or described issues in the days ahead. If anything seems significant enough to be shared, I will try to remember to update this post.FYI, my iPhone is a 15 Pro Max, and my car is a 2021 Subaru Forester (Sport trim).

I purchased this item for my 2021 Lexus NX300 as the car came with wired CarPlay. The connection time isn’t bad, it booted up within 5-6 seconds after turning the car on. Usually by the time the Lexus distraction warning was gone Wireless CarPlay was ready to go. There was no lag between me using the touchpad in the car and the reaction of the cursor on the screen for CarPlay. This is a great concept, but the execution has much to be improved. My issues with this product are:1. The quality of the audio. I noticed when using the wireless CarPlay, my car speakers had poor audio - little to no bass and highs and lows got crackly/almost inaudible. Switching back to standard Bluetooth or wired CarPlay did not have this issue. I listen to a lot of music and this was a deal breaker for me.2. Lag when switching songs. I skip around a lot in my playlists and library. The lag is easily 1-2 seconds between pressing my steering wheel button and the audio/display catching up in CarPlay. Again this issue is not present with Bluetooth audio or wired CarPlay.3. Interference. This device accepts A LOT of interference while driving. It would happen often where I’m driving and the audio will cut out, crackle or even lose the connection because of some other signal (perhaps police radar, stronger wifi bands near by etc). I found this to be very annoying and distracting.4. This is an edge case, but there are instances where I leave my car running and get out with my phone (for example to go into Starbucks while my friend waits in the car). Once I walk away and come back, the device does not reconnect to my iPhone. I can turn off/on wifi and Bluetooth on my phone and nothing. I have to physically unplug the device from my car and reinsert it to power cycle it. After a minute or so it will reconnect to my phone. This is probably the most annoying issue.5. Back up camera black screen. After reversing and shifting to park or drive, my screen will be black for a few seconds I guess while the device reloads CarPlay. This happens quite often and can get annoying.6. Battery drain. Not an issue for this device in particular, but wireless CarPlay SUCKS your battery dry. I download all my music in Apple Music so I’m not even streaming, but the wireless projection of CarPlay absolutely kills my battery on my iPhone 12. Add navigation and forget it. Just throw your battery out. I suppose you could use a Qi charger while connected to Wireless CarPlay, but that seems idiotic in my opinion. At that point just plug the damn wire in and call it a day with wired CarPlay.7. Song seeking issues. Sometimes a song would end and the next song would begin but 10 seconds into the song. I’ve never had this issue with Apple Music in general or using Bluetooth or wired CarPlay. Very odd.8. Phone call confusion. My iPhone wouldn’t know which device to connect to to route a call - my car, the phone, Bluetooth or the Wireless CarPlay receiver. Frustrating.9. Slow disconnect. I shut off the car and it takes a good 5 seconds for my phone to disconnect from CarPlay. This can be annoying especially if you have DND while driving enabled to automatically enable while connected to your car and disable when disconnected.All in all I wouldn’t recommend this device for the above reasons I stated. If you absolutely need CarPlay, plug it in with your wire. If you don’t mind the above issues I mentioned then purchase this device and see how it works in your own car. The cons outweigh the pros in my opinion.
