i bought my legacy system second hand, it works great but was on version 1.3. I bought a black module from Charles Ro which has 1.6 on it. I've tried to update the legacy remote and the red light flashes for over 5 minutes then reboots but still says version 1.3.
Do do I need to incrementally update the system? (1.3 to 1.4 to 1.5 etc)
