The seller does not provide the instruction manual. The phone application does not download contacts from the phone. It is not possible to make calls from the steering wheel with the voice like on the Hyundai car radio.
I am so satisfied with this Product. Believe me you will not regret buying it at all. The display screen is surprisingly awesome! The screen is very responsive and fast. I have just upgrade the firmware (Note: I got an error when It tries to update, I solve it by doing factory reset for the device). I really like the Unit Interface design it is so delightful and colorful. I have the best shopping experience with Teyes Store, they are fast at replying (Almost within 7 hours). You will never regret buying it. I recommend the product and this store.
