An alternative to the Fobo style TPMS is a Orange Electronics M203T TPMS system. I installed one on my '16 Road Glide Ultra. It has its own display and it uses "in tire" sensors (like the CVO uses) that fit my factory rims no problem. Does not require any movement to start registering tire pressure when first turned on. I wired it in so when I turn on the ignition it comes on.
You have to figure out how/where you want to mount the display, because it doesn't come with a mount, other than double stick tape. I made a mount for mine. Warranty covers sensors and display for 2 years, Cost $175.00, replacement tire sensors are about $35.00 each. I got it thru RRRToolSolutions. I've had it for 3 months so far and it works great... check it out if it's something that interest you.
