Do you have to update the nav to get the correct DST dates ?? I thought the dealer could give you a bios update or some other computer update, but apparently not? Mine changed 2 weeks early. I read some other posts but no clear understanding if there is a fix??

 

Yes, the dealer is supposed to have a DST only fix DVD. I believe this was listed in the AcuraService news, but no time tonight to look.

If you install 4.64 or higher you will get the functionality change.

The original functionality change was in 4.62, but as we know, that caused its fair share of software errors, some were recoverable from the diagnostics panel, other not.

4.64 was the first retail sale of the fixed system, although several implemented 4.63 which I believe was first introduced with the TSX, but it did not necessarily contain all the flash upgrades for the RL earlier versions, especially 4.1X and 4.3X.
