Backup Camera - Can you retrofit existing GL450's
Many GL owners took delivery of their GL's before the option was available...
Now that it is available, is it possible to add this feature to an existing GL? I'm more interested in MB doing the work, rather than an aftermarket product, but would like to hear from anyone who's done it, factory or not.
