Ordered Item was delivered ahead of time ,However not happy about the price charge for a "superior" DAB Ariel that turned out to be a standard type easily bough at a good £20.00 below ordered price. No reflection on car Radio Center but Pioneer are 'pants'at producing an instruction booklet.It might be in 20 different languages but get a grip on customer needs. Why comment on that - because DAB does not auto tune and responds with an error "no signal" ,.So dashed am email to Car Radio Center (Sales) team to see if the "Superior " aerial or the unit could be at fault. within 24 hrs I was informed that all the aerials were the same! and contact Pioneer under repair plan .Luckily I rang then first and they gave the info that the instructions committed to start DAB. I'm pretty sure that the responsibility for goods sold lies with the seller not the manufacturer.Other wise you might be Very Good.
