 My Synch never worked properly from day 1.The phone constantly froze up which brought the whole system down...the phone, radio, navigation.The dealer told her it was not compatible with her phone....a one year old Blackberry?She went out bought a new I-Phone and had the dealer program it.Same problems.Now they say it was a software problem. Replaced/upgraded software and the problems continued.It is a dangerous situation caused by the distractions of the malfunctioning My Synch.The voice activiation never gets the commands or the names right, so it might as well not even exist.Last week vehicle caught fire due to defective valve.Never want to see car again
