Had a new issues pop up the last few weeks. I have an 03 Denali with the bluestar unit in place for 3 month now. I have experienced the occasion drop when answering with the talking mouth button and the bluestar not recognizing the phone is still on, but recently I have noticed that anytime I have calls running in succession, (i.e. on call, then hang-up and dial new call) the unit has been locking up. The side effects of the lockup has been no response from the mirror buttons (led may be either red or green) and the instrument panel will flash for a second then the "stability control disabled" will pop up on dash panel with warning lights. Once I stop the vehicle and turn off the power completely the unit resets and all warning lights and indications become normal. I've been able to repeat this three times now (by hang-up of current call, then start a new call). It is as if the radio has an issue with switching between phone mode and radio mode to quickly it causes the lockup, of course the traction control error is somewhat concerning. I've disconnected the bluestar unit and replugged the OnStar back in so as to ensure I'm not dealing with another issue. When on OnStar I cannot get the error to happen again, so at first impression, it is something originating with the bluestar unit. Any tips? Is there any way to log the actions to send for troubleshooting? Any help would be greatly appreciated.
By the way, the phone is Iphone 4 and the radio is the stock Bose system that came with the Denali.
