Just as and additional comment to 4 sensor system and factory integration question..
I personally own a 2008 Jeep Wrangler Unlimited Rubicon. With a factory TPMS system installed, it requires 5 sensors. Installing this device, if it integrated correctly with a Jeep's computer in addition to the radio, it would show an error on the dash board without a 5th sensor. If it does not integrate, I could choose to disable the TPMS system at the dealership and use this product on my Jeep, while using the android radio or phone application as it's only interface. This would be a difficult decision for some customers like myself, since it would mean removing factory sensors and installing this system instead.
My question would be if your product has been tested to work with factory systems at all, or it should be considered as only a stand alone system for Car owners that do not have the option of a factory TPMS system?
I was recently faced with this problem as factory TPMS sensors go bad and can be replaced with aftermarket products in many cases, but they usually must be replaced by matching TPMS sensors, meaning all sensors have to be either aftermarket or factory, but not both in the case of my vehicle. Clarifying if they are able to be seen by factory ECM's would be helpful to many customers.
I also hope this helps other customers with a Jeep, because without 5 sensors, the dashboard will display a TPMS error (at least on my year and model).
