What is the date or version of the latest nav update for the PCM2.1 cars? I have a 2006 CTT with outdated maps, and I have seen one dated 05-2007. Is this the latest or is there a newer? There appear to be many p/n to order the nav update...
TIA,
Sal Carnevale

Probably not what you want to hear but I had the same problem with mine and what you're seeing is the factory blackish-bluish coating scratched/peeling off of the screen. There is no way to restore it short of removing the whole radio unit from your dash and sending the unit to Becker USA for screen replacement (I was quoted an estimated $350-400 by them worst case to do this). The alternative (which is what I did) is to remove the rest of the blue coating so that at least the whole screen looks unmarked and a consistent color. I used a Viva paper towel dampened with plain water to do this. It needs to be held over the coating for 10-15 seconds to soften it as I believe it is water-soluble. But then wiping across the screen with the same paper towel removed it and restored the screen look (albeit lighter in color like the part you have showing thru). I have noticed no ill effect to having it this way; it is still perfectly legible in all lighting conditions so I'm not sure what the purpose of the coating is other than maybe to match the color of the gauges?? The difference is most noticeable when the unit is turned off as the screen is no longer as black looking as it was. But I prefer this to the scratched-up look.
Hope this helps,
Sal
