hey all...i have a 2009 Sonata LTD w/Infinity head-unit (6 cd changer), the other day i went to eject a cd it gave me some problems. i finally got one CD out by pushing the eject button a few times, but the cd in slot 1 will not come out. i get "MECH ERROR", then it switches back to the last thing i was listening to. Does anyone have any insight into this?? Any help would greatly be appreciated.
