Firmware Upgrading Sony DAB (to allow parking sensors)


Recommended Posts


Got a secondhand headunit for my 63 Galaxy Titanium as the old one died.  They look identical, but the part number differed at the end (from FD to FB), and parking sensors are not working (but the actual sound from the radio is!)

But is there a way to flash the firmware in these headunits to enable such a feature? The parking sensors themselves are working (no flashing lights, and turn on when reverse is engaged), but no sound.

I don't want to rip out the cables and install a speaker just for this (as the signal should already be there..)


Is this possible? Any ideas?

The very last letter is the revision number. You can always go higher but you can't go back (as you now know).

So you could have replaced the 'FB' with a 'FD' and everything would have been fine. In answer to the question can you flash the firmware on the radio, I've not known it to be done by anyone here.
