Review on Hizpo Autoradio Navigation Mercedes Benz CLK C209 by Telly Roden

I bought this radio and also bought a D2B decoder box from another seller because my car has fiberglass and I installed it. The first day there was sound from the speakers and the next day the sound was gone. Bluetooth didn't work on my iPhone, I tried to call but there was no sound and the connection dropped. I've been trying for so many days and also got help from a D2B decoder technician but I gave up so I returned the radio to the seller and now it's been about 7 days and I still haven't received a refund. Customer service was good and understanding and they asked me to return it. Hope I get my refund soon.
