Hi, I bought a used Punto 1.3 MJD 2010 Model which has a video player without monitor. Now I would like to fix Monitor which suits to the size of the vehicle. I am expecting suggestions from senior people like 1. Size of the lcd montor 2. Maximum budget 3. Any additional things need to be fixed in addition to monitor. 4. alternate way to fix monitor without piercing roof, etc. Thanks.
