Input:
Question: Does the controls of the steering wheel work properly with the device?
Document: Definitely the product has serious problems and the touchpad does not work, so I can not calibrate or check if other applications are working properly, either the wheel controls work.
If I can get it installed, after reading the other reviews, I doubt the radio will work. Save your money and don't buy this product.
My wife had this on her wish list for Christmas, so I bought it. Kia actually had a model change for the 2011 model year, and this unit will NOT fit the 2010. They had to send me another unit, which would fit, but the wire harness was wrong. They then sent me a different wire harness, but the antenna will not hook up to the radio, and the brackets don't work. There was also no instruction manual.
The unit installed easy enough however it came with 2 year old maps and kept freezing. I was having to reset it it 1 to 2 times a week, all radio preset would have to be redone. Then the screen shifted to to right about an inch and a half. reset would not fix it. Finally had enough contacted the seller about a return. I had to pay $73.70 to return a broken radio to China before they would refund my money.
I have a lot of problem, i need to know how to reset the system, the Bluetooth is not working, change stations o song without to need it
Answer: Yes, they work just fine. You will only have to configure the controls before using them. Everything runs ok, the only thing i dont like of this radio is that GPS software is not included (it is ready for GPS, but you will have to find a compatible software to use it).
