I did have a word with the owner by name Santosh in the local lingo (He's Dharwad, karnataka based). He did assure that the steering wheel button operations in totally unaffected by the HU replacement and will work as same. Even the Blue & Me will work as existing with the BCM recognizing the HU without any alarm on the MID. The HU comes with a 1 yr warranty. The best part acco to him is that the HU is a simple plug & play, in case of any issues, you still have the old HU to replace stock. The only con in the HU is absence of CD player which will have to be compensated by the USB and SD card slots provided. In case of a sizeable number of order, the cost will be brought down, he even offered me franchisee for Mumbai region. Any takers with me. Pls note in no way am I advertising for the product, jut putting down the discussion details.
