Sat Nav Sd Cards

[salrom]

This must have changed because all the cars GTI, R & Scrocco except the one I bought had the voice control and I'm chasing them up as to why now.

Given that button can easily be changed between voice control and mute in the Mk6 using VCDS, that might be a simple fix later one when Ross-Tech get their hands on a Mk7 and document the new control modules.

I'd think the SD shortage would only be a problem for a short amount of time and shouldn't be ongoing in the months to come. I don't really like the idea of maps on an SD card - more chance of it disappearing.

I agree I tried to make a backup because I know how unreliable SD cards can be. I tried using a number of methods and none worked there is some kind of protection to prevent copping.

Try a sector-based copy? Perhaps from a live CD operating system?

Not many people realize but SD actually stands for Secure Digital. SD cards have some pretty advanced DRM copy protection available including protected data zones that can't be accessed. Its a rarely used feature on SD cards but I'm guessing VW is taking advantage of that fact (I don't think its been cracked).

Maybe you should try a smarter excuse to make a copy, like "in case I lose the original".

For more than a decade, I use SD cards a lot and never had one that failed.

Agreed — I've been using them since 16MB was a big one and no failures.

There must be a way to access the protected areas — back when prices made it worth their while the Chinese were able to fake the capacity in order to sell small cards as larger and more expensive.

I've had two SD cards die on me before. Well looked after - SanDisk ones, too. I own about 8 of them and use them almost exclusively in sandisk readers, Apple equipment and Canon professional camera gear.

Regarding protected areas, I believe the SD card uses similar DRM systems as DVD-Audio which has been broken now. I'll have my hands on a card when the new car arrives so I'll sit down to work and find out how this thing goes together.

Curious as to whether the Discover Pro maps are subject to the same limitations and how they are coded/locked to a particular vehicle. Chasing this up through various contacts; watch this space.

I've managed to download the latest maps from VW for both Discover Media and Pro, but I don't have a Golf 7 to work on.

Anyone interested in trying?

Backup the contents of the SD card first!
