2013 volvo s80 factory navigation retrofit

Q:
I have an 2013 s80 3.2l, without navigation. It has the 7″ screen and a cd rom.
And I was wondering if this is an alternative to the expensive Sensus Touch upgrade to get navigation in the car. And if it is could you share with me how hard is it to install?
Thanks!

A:I have to tell you that I have installed 3 of the census touch systems but I have had it for much less than what dealer wants but I have to say you could be disappointed with it after all, if it goes to that module I have installed few also and yes it is less expensive and works great, all you need is to install that module and download software thats all, it is if your s80 is nav prep just call a dealer to find out
