[SOLVED] Warranty Transfer

I'll have to ask to find out, but I believe the warranty only extends to the original owner unless you give them your original proof of purchase.

I gave them my original receipt from my dealer. Do they need to contact my dealer or Pioneer if it's transferable?

I've confirmed with the sales team; provided you have given the new owner the original proof of purchase indicating the location and date of purchase, the warranty is valid and there is no need to "transfer" anything. They're covered for one year from date of purchase.
