If people have not been to the Valentine V1 site https://store.valentine1.com/store/
recently, you should check it out. They have a product called SAVVY that plugs into the OBD port on the driver's side for power, but it also has a thumbwheel to set a speed that it gets from the OBD port. At speeds equal to or lower than what is set on the wheel the V1 chirps once at full volume and then immediately mutes. Great for calming automatic door openers. They also have another product called BOB that seems to be a capacitor to boost the voltage to the V1 while the auto stop-start is starting. I installed both, I did not try it without the BOB device, so I don't know if the X1 starting voltage would reset the V1 or not. I basically followed the same instructions presented here, but on the driver's side A pillar.
