Bad Luck: how long am I waiting for a new telematics module?

A week ago, the GPS and built-in data stopped working... right before a road trip to test out the Equinox EV range and charging. Fortunately, the range and charging have been great.

For those who have had their telematics module replaced, what has the lead time been like? I'm expecting my dealer to say that the unit needs to be replaced and is indefinitely backordered.
