Solve : SD & SDHC Cards?

1.	Solve : SD & SDHC Cards?
Answer» What is the difference between the flash memory storage CARDS SD & SDHC? The REASON I ask is because I have a Sat-Nav that says it takes up 4Gb SD cards. But as far as I can tell 4Gb SD cards are SDHC, now I have an 8GB SDHC and am totally confused as to whether it will work or not. (I realise that this is a computer forum but if it makes anyone feel any better then I'll let you KNOW that my Sat-Nav runs on Windows CE [and therefore must be a computer :p ].SD is older- SDHC needs different logic control. an SDHC accepting device can take SD- if it does it will be labelled with SDHC. if it is just labelled with SD then you cannot use a SDHC CARD with it.Is there such a thing as a 4Gb SD card then? censored? http://www.novatech.co.uk/novatech/specpage.html?RAM-SDM8G I thought that the point of SDHC was to break through a memory barrier?
