This is a replacement service for faulty Sierra modules for Panasonic Uconnect 2017 and newer. The unit (or Sierra module) needs to be sent in to us for repair.
The GPS function in your USA or Canada version Panasonic Uconnect model year 2017 and newer is handled by the Sierra module. If you experience GPS reception problems in an otherwise healthy unit, then this module is almost always responsible. Please consult us before ordering this product!
