Sat Nav Sd Cards

[Idle]

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!

i reckon those are European maps so don't recommend trying in Aus!

That's funny because I can't help but notice the folder called 'aus' and files containing 'Australia' within. Plus the dbinfo file with the same part number as people with 2014 maps on their Golf's, 5F0919866G.

If they are ROW 2014 they are Australian (and rest of the world - eg Not Europe and Not USA). You can download them from the South American VW Navigation site (but it takes ages). I believe that they are the same version as I have in My R now - as delivered (V2 ROW 0027 2014) - You can tell by looking at the DBINFO.TXT file - This matches the info from my car eg: ROW 0027 2014

PartNumber2="5G0919866G "
PartNumber3="5E0051236D "
PartNumber4="5F0919866G "
ApplicationSoftwareVersionNumber="0027"
SystemName=" ROW 2014 "

How compatible they are with all Australian models is a different question

Bingo thats where I got it from, and my theory is that since the DRM is encoded on the SD-Card for the Discover Media. You should be able the grab the ROW2014 maps from VW and upgrade goes through fine, since its designed that way in other countries.

readerr0r that makes sense. Everything I have researched indicates the licences (DRM) are attached to the SD Card. Somewhere in the manual it does say to update by downloading maps or by contacting a VW dealer. So I think you are correct. My only concern would be some references I have seen to V2 maps not being "compatible" with all cars eg:

V1 is for cars pre november 2013 built

V2 from then on.

Brendan i dont know how yours works. They cant be swapped around, it comes up invalid navigation data.

That reference is more related to when V2 was loaded onto cars from factory, not their compatibility.

I think the swap mentioned failed because each SD-card is tied to each car, not the map version. So a car's V1 SD-card upgraded to V2 should be fine, but putting a V2 SD-card from one car into a different car would fail. But of course its all theory until someone can give it a try and confirm it.

When I get my Octavia I'll definitely be testing out the Discover Pro map upgrade.

[zardoz]

Are there maps for the discover pro available as well as the discover media from that website?

Yup, but they're 17gb so you need to buy a 32gb sd card just to transfer them over. Its a small stepping stone for potential retrofits but it probably won't work without dealer interaction. I imagine a retrofitted DPro would still need to be authorized for AU maps. Updating a Skoda with one would be fine, since that's been done at the factory though.

Just gave it a try, the V2 map failed:- "Map Data is invalid, please insert valid media)" on an early 2013 unit.

Tried it twice with different copy programs, just in case...

Old data restored OK with Windows Explorer.

So there's more to it than we've discovered so far.

Rats, so V2 maps placed on the sd card had a similar file system structure to the V1? Good to hear it recovered fine.
