I have exactly the same problem as mentioned before.
Installation with old Nokia 6150 in the armrest.
How to change the final "interface" into one appropriate for new models?
Or how to re-arrange into bluetooth?
Thanks in advance
From a 6150 kit one would get "up to" a 6310i with a SW update to the PSE. A guy working at the PSE manufacturer did that, don't know if there is any official MB support, perhaps a new PSE would be the official option.
