imnio

I have a 2013 Ford edge without a Nav System. I am looking to install both a rear camera and Nav system. Does anyone know: 1. Which are the best devices in the market which combine the two into a single screen (brand/model no.) 2. Which is the best place in Dubai or Sharjah to install the above as I do not want to cut any wires (to protect my 5 year warranty) and use only conversion kits Many Thanks!
