XTRONSCar Auto USB TPMS Tire Pressure Monitoring Alarm System for XTRONS Android Car Stereo GPS Player

I had to download the "StoreBao TPMS" app from the Google play store, as I could not find the preinstalled software through the menu options. As far as functionality it works fine and initial readings after installing were within 2psi of my gauge. After driving for a couple minutes accuracy will improve.Obviously, valve stem sensors are easy to install and replace batteries if needed. However, if you are concerned about appearance (which I am) then I would recommend finding the kit with the internal sensors and having them installed with your next tire change. My tires were still new, so I will deal with these sensors for now, but intend to upgrade at a later time.

I could never get this to work. Instructions are not helpful, doesn’t provide any information on what app works with these. I have tried 7-8 (and paid for) iOS apps and none of them worked, it never picked up any type of signal.

I bought this for my wife's 2005 Toyota Celica. We had upgraded her interior with a 10" floating Android head unit last year. As part of that, I thought it would be helpful for her to get automatic notification about her tire pressure. There were different TPMS units but generally, a lot of complaints about them not working. I figured then those were working with a bluetooth connection, so possible a more dedicated wireless connection should work better, so I opted for this unit.I first tried connection to my phone by using a USB-A to USB-C adapter. and putting only two of the caps on the tires It seemed to work ok, but then when I tried on my tablet because the font size on the phone was too small to read without a magnifying glass, it said it had problems connecting. I removed the two caps which were on the tires and then it seemed to connect ok. Not sure if that was the exact reason or not, but it seemed to work. Then I installed in my wife's car, and it seemed to work ok, but it was making the annoying beeping sound, so I opted to turn off the alarm until the next power off. I'm not sure which power off that is (for example, car, USB dongle, individual tire caps?) but then after that, they wouldn't connect (error in connection). After that, I decided to remove the batteries from each tire cap, and then it started to work again. I found I could turn the sound for the alarm off from the Settings panel, so I did that instead.Regarding them working, they seem to be 2-3 PSIs off. However, otherwise, they seem to be working ok. This is only after trying it for the first time initially. We'll see if they consistently work over time. One thing we noticed is that one of her tires was low. Through this TPMS, we'll be able to keep an eye on it to see if there is a slow leak or not, which is exactly why we would want something like this.One thing I noticed about this TPMS is the LED on the USB dongle is still on even after the ignition is turned off and the key is removed. It becomes a slow flashing LED but still working, which means it is still able to draw power from the battery as there is no apparent battery inside the USB dongle itself. At the moment, I have no idea how much power it is drawing. While I don't expect it is much, I don't want to risk that it could drain the battery over time. This is not the fault of the device though if the head unit is still allowing a device to draw power from USB even though the power to the head unit itself has been cut.

I love having this it makes it possible to check my tire pressure all the time

If not for the issues finding the needed app, this is an easy slam-dunk 5-star. It's more than a little annoying tracking down the app needed. How is there no link or reference to it anywhere here or in the package instructions??? You need "StoreBao USB TPMS", which isn't even in the Play store currently. So I had to go to an Android apk archive site and find the app there. This is pretty easy for me to figure out, but I'm an Android nerd. The average person would likely give up and return this. But once I installed the app everything worked perfectly, just plugged the USB receiver into my Android headunit, screwed the new valve caps in, and everything worked, no setup or effort required at all. Pressure readings appear to be spot-on and they change once the tires are heated up as it should. Removing the pressure cap triggers a warning that a tire is flat, so everything appears to be working perfectly.

Installed this to use with my XTRONS PST10ACH_L Android 10 head unit. One thing to anticipate is that until the car is driven a short distance after the initial install, the readings on the TPMS app will be bogus. That said, I also found that for whatever reason the labeled caps on the sensors were incorrectly placed, but that was easily resolved since the caps are removable to allow for battery exchange. I simply moved the actual sensors to the location indicated on the TPMS app as I reinstalled them one at a time with the covers on the appropriate sensors. I do like that the app will overlay a warning as a priority of whatever is running on the PST10ACH_L head unit. The alert is a red banner across the top of the screen indicating the problem as well as setting an audible alarm (both have settings to control operation). There are also settings for the range of readings used to determine out of range. In addition the readings can be seen to either metric or imperial units. I went with the external sensor as I wanted to ensure that the system worked as expected before committing to having internal sensors installed which I do plan to have done shortly. I will keep the external sensors as spares after inserted a paper barrier to disconnect the button cell inside the unit.

I purchased this one because I believed it would work with the app that came along with the stereo. But of course it didn't you'd have to go to the App Store and get another app.. The funny thing is that's the same app that comes with the cheap ones that you can get on eBay so why spend a big amount of money for something but you don't even see the name of on there so it's not even prestige and it doesn't work with the app that comes with the stereo deck just buy the cheap one off eBay you'll be saving money.
