I want to install an after market Navigation system to the 2015 RX350 but could not find the manufacture part number of the Navigation system for the 2015 model or if the previous year Navigation models (2012, 2013, 2014) would be compatible with the 2015 RX350?
I thought in theory, all one would need is, installing the GPS antenna and a GPS software + (possibly update the GUI) into the current hard drive; assuming there is a connection for the GPS antenna in the back of the non-Navigation console. Wonder if anyone know if this is doable? This would be the best and least expensive option, or
Would I need to buy an entirely new 2015 RX350 Navigation console? Or, would 2012, 2013, or 2014 console compatible? i.e. Lexus has not changed the part (the Navigation console) between these model year?
Greatly appreciate your help (hopefully I figure this out before my wife realize that I bought her an expensive new car without a Navigation system. (Note: My dilemma is that she does not like the tangled-wire or a separate handheld/portable Gamin or Tomtom navigation “thingy”!)
Thank you for your input and advice
