Hi Folks,
Have tried to get info re this from Hema but have been put on hold far too many times and have had no response to an email request.

Can an SDHC 4 gb card be used in a 4.3 H N ? The original 2 gb card is just SD.

Have been informed at several stores that anything in excess of 2 gb is only available in SDHC format.

Any advice greatly appreciated.
Thanks.
Jon W

Jon

You've been advised correctly. The early GPS models will only use SD cartds and these are available up to 2gb.

There are 4gb SD cards available. They're getting hard to find but they do exist and will work in SD only devices. On ebay occasionally.
My noname GPS works with a 4gb SD, won't work with a 4GB SDHC

Hi Jon,

I'm using a SanDisk SDHC 16gb in my 4.3 HN, so I don't see why not.

Cheers,
Darren

Thanks Darren.
Was it just a straightforward copy from the 2 gb to the 16 gb and then insert the 16 gb back into the unit?

Yes exactly that. I actually copied the original 2GB card to a directory on my laptop (just for backup purposes) and then copied it onto the 16gb card.

Darren

There were 4 gig SDHC cards in the three 4.3" units I have used. From memory the 4.3 unit had been tested to 8 gig. Stand to be corrected, it might have been 16 gig. Anyway a lot more than 4. Only the earliest 4.3 units had 2 gig SD cards.

Anything above 2 gig ie 4, 8, 16, 32 must be in SDHC format. In the early days of beyond 2 gigs there were a few cards of 4 gigs that did not conform to standards and should be avoided. Insist on SDHC above 2 gigs. Doubt the non conforming cards are still being sold. Possibly may surface in second hand market.

Perhaps I should clarify the non conforming cards 4 gig SD cards would not have been used by Hema. I was talking of SD & SDHC cards and conventions in general.

The SD standard does allow a 4GB SD card. Some equipment did not conform to the SD standard.

Not according to this information from the SD Association.

http://www.sdcard.org/developers/tech/

As I recall ersatz 4 gig SD cards did not conform to SD standards and were marketed before SDHC standards were finalised. Once the SDHC standards were finalised they seemed to disappear off the new market.

Over time the standards have been revised. Rev 1.X supported 4gb SD, replaced by Rev 2. where 4GB became SDHC.

From http://en.wikipedia.org/wiki/Secure_Digital

"The SD Card Association's current specifications define how a standard SD (non-SDHC) card with more than 1 GB and up to 4 GB capacity should be designed. "
