stock stereo upgrade and interior lighting
 

I have a 2007 Maxima with the Bose system.
If I am correct there was a touchscreen system offered in 2007 and/or 2008. How hard is it to change my stock Bose system to the stock touchscreen?
Also I am sure that in 2008, the Bose system was offered with Satellite radio, how hard would it be to at least change my 2007 radio w/o satellite to 2008 with satellite?
Finally, has anyone ever changed there interior center dashboard orange light bulbs to another color? I am looking to change mine to more of a white color to match the stock gauges.

Is this what you are talking about?
