Well.... this is odd. All 40th's came with the Bose stereo system. Why don't you have it? Especially since you've got the leather-heated seats it means its a "touring package", which comes with the Bose automatically.....

When I bought the car the stereo was misisng I didnt know that I had to buy the bose stereo instead I bought the regular one.. im thinking to get a touch screen stereo will it work or need bose stereo system oem ?
