Update the database in it, generally helps and many times fixes it up.
Be advised if you use a favorite list, it will not update that as its user generated.
Your database date is found by pressing MENU button on the left side of the radio, the red button, scroll with the top knob to manage full database, press E button and scroll to Information and press E button to see how old it is.
Then press Menu a few times to get back to scanning.
Other day updated someone's brand new sds 100 and 436hp that came with June 2018 database info!
@JoeBearcat need to have a more recent database and more recent firmware in all zipcode production units.
