My HUD works great most of the time. It works "as advertised"---I'd say 60% of the time. It displays exactly what the documentation says it will---speed, temp, gear, etc., and also NAV information and radio information coming from the NAV radio. When there is a NAV maneuver coming up, it displays the maneuver and provides the "distance" until the maneuver. When XM radio changes tunes, it displays the new song title. When on AM or FM, is shows the station number. In summary, it works just fine.
BUT..................
Sometimes it doesn't work. The info from the "dash" (speed, temp, etc.) works fine all the time. But the info from the radio sometimes works, sometimes doesn't. There doesn't seem to be any rhyme or reason as to when it does and when it doesn't. I (and others with the same problem) have checked all options and that isn't the problem. My local dealer has witnessed it and has a "case" open with GM trying to understand and find the fix.
If you have the problem, chime in here. When someone gets it fixed, let us know. If GM is reading this, let's help them understand the problem.
