HUD not working?
 

I got my toy (2012 2SS/RS, convertible) out of winter storage yesterday. The heads up display (HUD) isn't working and either is the close proximity back up alarm (beep beeep beeeep). It was winter stored in an unheated garage, but with a battery tender on it. It started right up, so I know the battery is in good condition and never went dead. I had a new GPS antenna installed just before it went away. The Stereo is a Pioneer AVIC8200NEX, installed using a Radio Pro RPK5-GM4101 dash kit. It was all working last year (I think, when it went into storage). Does anyone have any ideas? If not, can you tell me where I might look for help

i never use mine. worries me it will stop working.
