[BC] What is

[DANA PUOPOLO]

Yep..
and remember, every radio that locks up during s firmware update needs to be
brought back to the dealer (store, etc.), removed from the dash, repaired and
reinstalled.

I'm sure that Circuit City, Best Buy and all the car dealers will be THRILLED
to have to put out a few hours a week (unpaid) for this kind of work....

Yep. Moreover, the upgrade process is not 100% foolproof, even if the 
upgrade code itself is bug-free. Starting with the 8400, Optimods have been 
field upgradeable via a PC download through the serial or Ethernet ports. 
We get an occasional unit where the EEPROM runs into problems during the 
upgrade and needs to get replaced at the factory to restore the processor's 
functionality. Since we started doing upgrades this way, we've learned 
quite a bit about how to do these upgrades reliably, including always 
keeping a backup copy of our system executable on the EEPROM so that the 
unit can recover as long as the BIOS is still intact. But in the case of 
the 8500, storing a backup requires an extra 6 MB of non-volatile 
memory,  which is not a problem in a product in that price range but 
probably is a problem in the consumer electronics industry, where every 
fraction of a penny in the bill of materials gets counted.
