TMC & Mic question

After the update to the latest version of my PN4000 it recognize
the TMC channels but it doesnt get the information (on the screen).
Version 528570_PSN_1.7.3.2.ZIP

Some one familiar with this ? Where can i download older firmware ?

The other question is :

Can i use my old Nokia carkit microphone on the Craddle ?

And if not, what external microphone can i Use ?

Regards,

TMC works now after reset to fabric settings.

I cut off the edges of the Nokia Microphone and now it works.

But the recorded sound is pretty terrible

Some1 got the same thing ?
