Bad news. Unfortunately, Joyeauto contacted me saying "Our cooperation is terminated! because you leaked the price we negotiated" WHATEVER THAT MEANS! I really don't know if they back out on their offer or just playing games... Shame!
I will refund everone's money. I really wanted to make all of you enjoy CarPlay at a reasonable price. If you want the same Wireless CarPlay features, I would recommend this company...
