I just downloaded X431 Idiag American GM software into my IPhone 4S. It appeared to be a successful download and showed paid and completed. The GM diagnostic program opens and scrolls through selections but freezes when it goes in to read data on modules. "GM diagnosis reading for data please wait" screen freezes. I have tried GM on 2 different cars without success. My other Launch programs work fine on other selections such as, OBD2, BMW & Benz. Did something go wrong during the GM download? I have checked the phone and have sufficient storage space. Thanks
Please note the X431-I Diag software is only intended for use on OVERSEAS units originally sold or distributed thru CHINA LAUNCH and NOT the same as the Launch Tech USA EZDiag software for apple iOS devices. If you have the X431 IDiag you must contact CHINA LAUNCH for support.
