thanks for writing back. Looks like they are up in Petaluma. I was looking for someone down in So Cal...
@pulltab did you have any luck finding a Prius shop in SoCal that can perform the cruise control for your C1. Encountered another C1 looking for a similar upgrade. Thanks!
Thanks for writing, I have not found anyone in So Cal for that installation. I have read follow up comments here, but I am kind of squeamish around the steering wheel especially disassembling it....
I put one in my 2015 prius c 4. I have no regrets. its been over 2 years and I still love it. worth every penny. The crew at OEM are great to work with. Especially Daniel. Good Luck
