MB-Pilot

I currently have the Nav +4

Can this be switched to the bigger screen ? Jut throwing it out there to see.

Also, I dont have the garage opener option, am I stuck with this mirror or does MB carry a mirror that can be switched?

I think its more complicated than simply switching out the rearview mirror. The mirror also has auto-dimming, so it also hooks up to a sensor. I think it is best, financially, to invest in a $10 garage opener.

What about upgrading the screen to a bigger one.

I saw on youtube that you can go from a 5 to a 7 on my type of c300.

Anyone ever attempted that?

The cost of going to COMAND from Audio 20 may be way more than you might be willing to stomach. Nav+4 may be a very basic system but it works well and has a good ipod interface and bluetooth stream which only became available on COMAND in 2012 on the C class.

I do use the bluetooth audio streaming capability but it takes time to play.

I launch pandora and it takes about 30 seconds for me to start hearing any sound, it does a skipping sound . Plus with bluetooth ,you dont get artist and song info.
