Likely story.
I wish you the best of luck but these kinds of things often end badly.
My bet is that they will offer you a refund and leave you holding the bag.
Thanks for the well wishes. If I was a betting man I'd take you up on your bet. Supplier has shipped me two Canbus filters, one for each headlight, that I will connect between the LED headlight and the OEM wiring harness. Hopefully that will fix my radio reception issue. I'll post about the results.
I've had nothing but world class customer service from this supplier. I know him and trust him. BTW, supplier providing/shipping filters at no cost to me. He is truly interested and committed to helping. Couldn't ask for more!
