Thanks. Mine was a "7", changed it to "9" for 4-flashes, 2 days later returned it to stock as I couldn't get used to the extra flash .
Well I put a 1000 miles of freeway with 5 blinks and it is working for me. I tend hit the blinker and then shoulder check. Sometimes there is someone really close and it takes a bit to change lanes.
I was going to do the reverse passenger side mirror tilt, but using the 3rd seat preset seem like a good idea.
