I think they are going over to a new standard soon, making the current ones obsolete.
I wonder why car manufacturers have been so slow on the uptake?
Absolute nonsense, this is how rumours start.
What you have probably read and clearly mis-understood, is there will eventually be a change over from analogue to digital radio the same way as TV is changing.
For Radio Its a few years off yet, but in the meantime the roll out of DAB services continues for those that want to make the change now.
The reason the car makers are holding off is because of the lack of a standardised system for markets other than Europe. The car audio makers for the same reason. (Alpine, Kenwood, Sony, s biggest market by far, is the US)
The USA has been trying to promote a satellite based systems for 10 years and they believed that it would be be adopted in Europe. But as we don't have the same population spread issues as the USA, a land based system is cheaper and easier to install.
The car makers wont make a move to fit as a standard until the demand is there. However, It is available as an option on top line German cars now.
