From Sandisk Customer Service:
Jennifer G.: We have verified a couple problems with using SDCZ43, SDCZ93 and some builds or SDCZ48 when used with car stereos. Some car stereos may not recognize the card or will playback songs at a higher tempo. We expect a fix for this issues to be put into production shortly. There will be no field firmware update available for this.
Me: When do you expect for it to be available?
Jennifer G.: We expect to have stock in 2 weeks that will work with your car stereo. At this time we can offer to notify you when stock is available for exchange or you can return the drive to the place of purchase.
Me: How do I know if I am getting the newer version, or the same defective version?
Jennifer G.: Yes there will be a notification to you through email and then we will replace your defective product.
Me: Sounds good. Thank you.
Hopefully, that will happen. Looks like more than the Ultra Fit are affected.
