Doesn't seem the way to run a business. Not everyone wants to use a shop or they don't live near one of these certified shops. There limiting there clients. Do you work at one of there shops that have been shown the way? Please give details.They have no problems showing a shop how to do it, but they just say unless the shop has seen how it's done then they won't be able to work it out.
I can't say enough about PCS I was wanting a few more inputs and outputs to make everything on the dash function as stock with dash lights and such. They shipped out more wires with connector terminals free of charge
