Default Using Secure Digital (SD) Cards in the Skoda Superb

I want to use a Class 10 SD card with the Bolero entertainment system in my Skoda Superb 1.8 TFSI A/T to improve upon the transfer speed that I get from the Class 4 card. However, before buying the new card from the UK, I wish to confirm whether the car's music system can handle the all-new Class 10 card.

Any suggestions/inputs please?

And why would you want a Class 10 SD Card? Are you sure that the transfer speed from a Class 4 card - which is anyhow way too fast for music playback - is insufficient for your needs?

Yes, I do as it takes the Class 4 up to a minute to switch to another singer when I use the "selection" feature of the system. The question now is whether Superb's system can handle the Class 10. I wrote to Skoda but they simply asked me to contact the dealer, who in the first place had asked me to contact Skoda. Wonder why Skoda can't answer a simple question like this without making customers run around back and forth?

That's a conjecture, sir. The issue is with the HU's ability to do list processing, not with the transfer speed of SD Card. Have a heart, the HU processor is not a PC processor. It is a very low power controller from which one should not expect even netbook level performance.

At 4MBps (MegaBytes/s; 32Mbps), Class 4 cards are good enough for Full HD Video recording. You can definitely put in a Class 10 card in its place, just that the reader in the HU will read it at a speed that it needs to, not what the card is capable of. Transfer speed of an SD card matters only when you want to write to it (Class represents the MAX SUSTAINED WRITE SPEED), like still or video frame recording. Read speeds are always in excess of the fastest write speed of a card.

You are wondering about their attitude, but you haven't questioned the knowledge of the people you asked a question to. You may take pride in your knowledge and customer satisfaction consciousness - just don't expect that by default with dealers and car companies.

Also, they know only about the car, not the accessories, forget which Class of SD card has what relationship with the HU. Wrong expectation on your part.

We found some HD camcorders need Class 6 cards to do full (AVCHD video file) HD (24Mbps) and at Class 4 fall back to 17Mbps. Why? We dont know.

Still Class 6 is more than adequate for full HD video.

Class 4 is about 32x. Class 6 is about 48x.

Like DA said you Hu's processing is the limiation. A faster card will not help.

I have a 8GB Class 4 SD card which is now almost full. While it was working fine earlier, lately -- after I downloaded some more music -- the music breaks when I switch between folders. Within a folder, it works normally. The card, however, works fine on my laptop. Any suggestions/solutions please?

Thanks Navin. The card was working fine between folders when the download was about 5GB. So what should I do? Reduce the number of songs? Or what?

I recently bought 16GB microSD Card. Not all files are getting copied, some folders are missing. When I use it in my camcorder, it records the videos, playback works fine, but when the camcorder is turned off and on, it asks whether to format the card and the files are lost. Tried with different usb adapter to copy the files from the computer, when the card is safely removed and inserted again some files vanishes, don't know what is the issue.

Before using a SD card in a camcorder it makes sense to format it on the camcorder.

If you reduce the songs you dont really need a 8GB card na? 4GB cards would suit your HU better.

I am not sure what this 'Class 10' spec is or means but I use a simple 2gb SD card in my Superb and it is very quick. No real lag in loading, infact it is quicker than a CD in terms of loading.

@Sahil - Class 10 signifies the read/write speed of the SDHC card (similar to the 40x , 133x etc of SD cards)

Class 2 is the slowest, and the higher the Class the faster. Currently the fastest available card is Class 10 if im not mistaken.

Class 2, 2 MB/s, slowest for SDHC cards.
Class 4, 4 MB/s.
Class 6, 6 MB/s.
Class 10, 10 MB/s.
