Finally Working! – Lexus RES+ Review

After months of frustration, the dealership finally got this working. The error I always received was, "Communication with the vehicle was interrupted. Please try again later." When originally installed, the dealership left the system in "service mode". Once they took it out of service mode, then disconnected and reconnected the car battery to reset the radio system, the RES+ finally worked consistently. It is slow, but it works on my iPhone 5s and my spouse's iPhone 6. Hope this helps.
