Question about installing Navigation in new car.

Sorry if this has been asked before but I looked around a bit but couldn't find a exact answer to my question.
I recently purchased a 2014 c350. It has audio 20 with Becker map pilot. I had a 2012 c300 prior to this car and it had the built in Comand navigation. Well after driving the new car for a month I just can't stand the becker map pilot. It is cartoonish and more importantly it lags when giving directions. So I miss turns all the time. I also miss the other options the built in Comand offered & the bigger screen really made a difference.
I am the first one to admit I made a mistake by trying to save a few thousand bucks but I'm just not happy with the audio 20/becker map pilot. I was told by my sales person that the Becker Map would be comparable to the built in Comand navigation in my old car but it's really not.
So my question is can the built in Comand navigation be installed in my car? I know it will be costly but I plan on keeping this ride around for a while. I want to fully enjoy it. So is it even an option?
Than you in advance!
Unfortunately Becker Navigation cannot be upgraded to Command, even at a price. You can hope that the next Becker software update/upgrade will make it work better.
