I don't even have 300 miles on my 2022 TRD and the I'm getting "check antenna" message on XM. I'll take it to Toyota but what would this be? It was working fine then started to sporadically give the error now it just stays on.
Wrong. Loose connection is not possible. It’s a clip on plug on the antenna. The only time the check sat antenna message is displayed is then the actual antenna is bad. I’d it’s not connected it will display no antenna
