Hi, new to this forum.
Need help with codes on my new CLA. Have asked the dealer and tech but they have no idea what the difference it is.
My question are:
Code "355 Preinstallation for retrofitting navigation system" on the new CLA. For my other car it has coded 355 Extended MBUX functions.
Is my new CLA missing a navigation system or something else? Or it will be installed when the car arrive at the dealer?

Code "548 Connect 20 MID (NTG6)" vs Code "549 Connect 20 HIGH (NTG6)" What kind of function is it missing compare to HIGH?

Thanks for helping!

I'm confused... are you asking about all these codes on one car? It sounds like you are asking about multiple vehicles.

Sorry for the confusion.
Just want to know what "355 Preinstallation for retrofitting navigation system" mean.
And what 548 Connect 20 MID (NTG6)" is missing compare to 549 Connect 20 HIGH (NTG6)
