Guys, Kindly suggest which out of the following DVD options is worthy and why: 1. Roof mounted DVD Screen. [Might require change in HU which I do not want. Additionally, this may mean some damage to the roof, and that is a big no-no] 2. Headrest mounted DVD Player and Screen. [No option for dual screen. Non messy but audio output through speakers will be not good due to the FM modulator.] 3. Strap-on DVD Screen. [Option for dual screen available. But no good brands available in India which can also provide warranty. Messy wire work. Includes a conglomeration of multiple accessories which makes this vulnerable] Thanks to all for their inputs.
