    I have a shiny new 2024 Prius Prime plug-in, which I mostly love, though it's super weird that they don't have a rear wiper.

    Here's my question. Most of the time, the car connects politely to my smartphone, and starts up Android Auto, and everything works just fine. But every once in a while it doesn't. The most obvious example came up yesterday, when I started the car, realized I'd left my phone in the house, put the car in park, and ran inside to get it. At this point, obviously the car hadn't been able to connect to the phone because the phone wasn't there when I started it. Is there any way to say "please try again to connect to the phone" short of stopping and restarting the car? No problem doing that when I'm sitting in the driveway, but sometimes I don't realize it hasn't connected until I've driven a little way, and at that point it's inconvenient to stop and restart.

    Two ways.
    1. (I'm going from memory, so this won't be totally correct, but it should be close enough to get you there.) Tap the gear icon, tap personal devices, select your phone, tap connect to device.
    2. Press and hold the radio power button for 3-5 seconds. This will reboot the head unit and it should then automatically connect to your phone.

    Thank you! I'll give that a try.

    The reconnect option almost never works for me. I just do the reset by default now.

    I find the AppleCarPlay very temperamental on this car, more than my other cars.
    It'll drop then re-connect or won't connect at all.

    I've done the reboot a few times. Works for a while then back to the same past behavior.

    Rebooting by long-pressing the volume dial works like a charm for me. Once it gets initially connected it seems to stay that way just fine. Thanks for the help!

    There seems to be no rhyme or reason for when it decides to auto-connect to my iphone and when it doesn't. I have to manually connect through gear icon-> Bluetooth -> my phone -> Connect about half the time I get into the car. Sometimes I have to hit connect 2-3 times, sometimes it works on the first try. Roughly four times in the last year I've had to shut down the car or power cycle the radio to get it working. Doesn't matter if the last driver was me or my spouse or whether or not the app wanted (and given) permission to connect to the phone thru the pop-up. Different times of day, different locations, different weather, etc etc. It behaves like this for a few days, then is works fine for a few, then acts up for days. I am the primary driver and listed first in the list of devices, though I don't think that matters. My spouse has the same issue.

    My bluetooth is always on because I have a medical device connected to it, so it's not like the BT is in sleep mode or anything.

    This isn't really your issue since your phone was too far away when the car was started - sorry for hijacking it to whine! But it's the only forum thread that I'm aware of that brings up this issue.

    I wonder if this might be the reason for the issue? The phone might be prioritizing communication with the other device and not handling the handshake with the car properly.


    As an aside, I'm often amused at how people tend to automatically blame the car and not the phone when there are issues between them(namely connecting and charging issues). Isn't it just as likely that it's a problem on the phone's end? Like the issue with the wireless phone charger. There is a pattern emerging that the issue is only with a couple phone models(S22, iPhone 13). Isn't it more likely that those two models have some tiny flaw in the charging handshake module that triggers the car's charger. There are communication standards that govern that hookup, and maybe those couple models of phones don't completely comply with the standards in some small way. Maybe some chargers are less stringent with the standard and allow the hookup anyway, but the charger in the car requires a perfectly compliant communication? Or maybe it's something else; I'm just spitballing here.

    The phone being too far away was just one of the times. The other reason it seems to have had trouble connecting is that the car couldn't establish a WiFi connection to my phone because the phone was still connected to my house WiFi. (Android Auto uses WiFi, not Bluetooth, to wirelessly connect to the car.) I *think* I may have fixed that, though time will tell, but it's a bit technical. I use Tasker to detect when the car's Bluetooth connects to my phone, and then, if there's an existing WiFi connection, Tasker makes it go away by shutting WiFi off on the phone, waiting 10 seconds, and turning it back on. This, of course, involves (a) being a Tasker geek, and (b) having an Android phone, because Tasker is a purely Android thing. But ever since I've had this in place, the phone has connected to the car perfectly every time -- when I've had it on me, that is.
