Yes, we can add the Apple MFI option after your Armadillo Tracker has left the factory after production. Please email support@houston-radar.com and request to add the Apple MFI to the serial number(s) for the Trackers. A quote or sales order will be generated along with an RMA number and return instructions. Once we receive the Tracker(s), we will test each device and install the Apple MFI hardware. The Tracker(s) will go through our Quality Control process and receive a new serial number since we are adding new hardware to the device. We will then return the Tracker(s) to you.
