Starting this thread to (hopefully) capture the collective experiences of folks using this device to connect Android Smartphones using Wireless Android Auto to Crosstreks Head Units. Everyone should start by giving "details" about their setup to make it easier to suggest changes and to help identify the source of any issues. We can use this thread to describe our experiences (Issues + Tips & Tricks) using this device. I posted some of my experiences with the MA1 in the "What did you do to your Subaru today???", but I wanted to start an uncluttered thread that could be use as reference for current and future Motorola MA1 users in this community.

Details as of 02/20/22:
Model/Year: Limited 2021
Head Unit: 8" with Navigation System + Harman Kardon Premium Audio - Firmware : Rel_UH.21.41.70 NAFTA
Smartphone Make/Model: AT&T Samsung S21+
Android Platform: Android 12 - Build G996USQU5BULJ
Android Auto (AA) Version: 7.4.120744 beta (AA Developers Option enabled)
Google Maps Version: 11.18.0
Waze Version: 4.81.0.4
Spotify Version: 8.7.6.1087

Most of the information that follows is from the previous post I mentioned above, but I have updated it with more current information. The info below also refers to the Wireless charger that I use in conjunction with the MA1 as shown in the picture.

I'm very happy with my Motorola MA1 setup. The MA1 allows me the convenience of taking off my jacket (as I do when I drive) and placing it in the back seat "without" having to take my phone out its pocket. No need to plug the phone to the USB cable in the car and then place it on the seat side saddle... where I always forget it. I can't count the infinite number of times that I have to get back to the car because I left my phone behind. When it's cold, I never forget my jacket. I also found it inconvenient to unplug/re-plug my phone every time I use it to make contact-less payments at drive-thru windows and in some garages. Plugging and unplugging also adds undue wear to the USB port of the phone. This makes the MA1 wireless dongle worth every penny to me.

I attached the Motorola dongle with Velcro to the top left side of the cubby instead of using the adhesive pad that comes with it. This way it can be easily attach it and remove it. It's on the left side of the cubby because the pair/reset button of the MA1 is on the exposed side of the dongle. Btw, this button can also be used to switch between two paired phones. The LED light also faces the driver. The bottom USB port in the cubby is still available and the wireless charging pad has an additional USB port for charging that is easy to reach. (See picts) The wireless charger works well even while my sizeable Samsung S21+ is in its protective case. You can tell that it's charging either by looking at the LED on the charging pad or by looking at the battery icon on upper right corner of the HU. The wireless charging pad, is mostly to get rid of the USB cables for charging. My phone is usually fully charged when I leave the house. I also charge it while I'm at work or at my final destination. I have yet to test these wireless devices on a long drive, so I don't know how they will behave. I don't know if the phone will overheat while charging it and using the Bluetooth/WiFi/Cell connections on long trips. Given that the phone is in close proximity to the dongle... it "might" reduce the amount of power the phone needs to use to connect to it.

So far the only issues that I have encountered are: 1. When listening to Spotify and using Waze voice navigation, the volume is lowered, but the music stutters/skips when the navigation voice comes on. This issue is not as noticeable when using Google Maps and it does not happen when using the USB cable as the volume is lowered and the music continues without a hitch. 2. As time goes on, skipping to the next track also takes a little longer than when connected via USB which is bit annoying. This also happens with Google Maps, but it's not as bad. Hopefully, these issues will be fixed in future releases of Android, Android Auto and/or Spotify. 3. (This is related to the wireless charger) The phone can shift out of the charging position when you hit a bump or travel on uneven roads, but it doesn't happen that frequently to me. So, I wouldn't recommend the wireless charger for off-roading. I might try adding some sort of side clips to the wireless charging pad to keep the phone in place.

I have now been using the Motorola dongle for almost two weeks and will continue to test using future releases of Android Auto, Spotify, Waze and Google Maps and report my results here. I'm hopeful, that the issues I just mentioned will be addressed soon by the developers of these apps. I also have to try clearing the cache/data from these apps the next time I take a leisure drive. I have done this with previous versions of AA, Spotify and Waze, but not with the currently installed versions of these apps as I have no time to make adjustments as I drive to and from work.

If anyone has similar issues or found solutions to the ones mentioned above, please post your experiences/solutions.

Moderator, please move this post if it is not in the appropriate section of this forum.

do you have info on the wireless charging pad you are using there? model, where you got it from, and comments about fitment? Thanks!
Here is the Amazon Link to the Wireless Charging pad I've been using. It's called "CarQiWireless" and it's specific for the last couple years model of Crosstrek. Very easy to install as it was just Plug & Play. It charges my Samsung Galaxy S21+ even while in its protective case as shown in the picture above. The pad fits perfectly on the sides of the cubby with about an inch gap in the back. It doesn't move from side to side, but if you push the tray it will move. I was thinking of cutting up a piece of hard black foam to take up the gap if it starts moving, but so far, it has not been necessary. The phone stays in place while it charges most of the time, but as I mentioned above, it can move out of place when you hit a bump. If it moves out of charging position the green LED on the charging pad goes off and the battery icon on the upper right corner of the HU changes status. So far it's worked perfectly, but since I have not gone on a long trip or have kept my phone on the charging pad while connected via Android Auto to the MA1 for long periods of time, I don't know if the phone will overheat.I believe that removing it temporarely from the charging pad will mitigate any overheating issues. Also, the charging pad has a power button to turn the pad on/off manually. The pad "should" also turn off automatically and the LED will light up in white to indicate that the phone is fully charged, but I have yet to test this functionality. The other convenience of this charging pad is that it has a USB charging port on the front, so there's no need to reach back in the cubby to charge another device via USB cable. Below are the pictures I also posted in the other thread.

AA/CarPlay has always required that the phone be plugged in with a USB cable. The only changes I'm aware of are that they moved the active USB ports. Ours are in the armrest cubby. I suspect they moved them to the center console cubby to shorten the cable length and improve connectivity.

BT is only audio, no AA/Carplay, unless anything has changed lately or these charging pads also have a way to connect to AA/CarPlay.

If the wireless charging pad doesn't connect to AA/CarPlay, I don't see much value in getting one.
The USB wired connection was needed for "data" connection to the HU for navigation (maps from phone) + to use the AA Graphics User Interface (GUI) from the HU instead of the phone. The USB cable connection was also needed to maintain the phone "charged" while in the car. The Motorola MA1 solves the "data" connectivity to the HU and the charging pad solves the "charging" function from the USB port to the phone without a USB cable. Two separated functions.

Audio/Phone functionality has traditionally used BT even without an infotainment HU. I'm almost 100% sure that the connection from the Phone to the MA1 dongle is via WiFi, but the "initial"configuration of the MA1 to the phone requires BT. Once the Phone connects to MA1 dongle via WiFi... the usual BT connection from the phone to the car is reestablished. BT only allows connection to a single device at a time. You can pair multiple devices, but only one can be active.

at first the adapter was working great for me, now not so much.
Something similar happened to me a couple times. What I do with the MA1 plugged in and the LED "flashing" green... is to go to the BT settings of the phone and select the BT id of your Head Unit to connect to it. Wait a little while and AA should reestablish a session with the HU. In my case, I believe it happened because at one point I used my wife's phone to test the MA1. Btw, I've been using General Availability (GA) Android 12 and Android Auto 7.4.xxxx betas. I joined the beta program for AA in the Google Play Store. Some of these later AA beta versions have fixes not available in the GA versions. Some of the recent beta releases have addressed issues with text messages notifications.

Edit:
You might also find some help in the Google Android Auto Community

These are some of Android Auto known issues that have been acknowledged by the Android Auto Team as of 02/21/22. I hope that the Spotify music stuttering over BT that I experience when voice navigation goes on is addressed in the next Android 12 Build for the AT&T Samsung Galaxy S21+ mentioned in the Samsung announcement.
