TIA |

Hi,
I have been looking to buy one of these as well and been sort of researching the various forums to see what people are saying.
As far as I can see, it does support SDHC cards.
However on one of the French/Swiss forums there are a couple of reports where people are having probs either copying maps across from the internal memory to the card, or getting their PC/Mac to recognise the card.
They seem to be few and far between and 4Gb cards are what they are all using.
Edit.
Not sure but the 930 may only support 1-2Gb cards, so this may be their problem ?? _________________ Triumph Tbird 1700. And now a Bonnie T100.

SDHC cards work fine in the 930, I have an 8GB card fitted to mine which is a little problematic in that you cannot write to the card whilst in the device, you have to remove the card and use a card reader. If I go over 4GB it doesn't work reliably so I wouldn't bother with anything over 4GB at the moment until Tomom fix the software to accept the larger cards (if it can be done) - Mike |

If it's tha same as the X20 series, it will read & write to the first 4GB, I'm using a 4GB SDHC card on a 720 with no problems.
It will read from larger cards, but you would have to write with an SDHC compatible card reader to the extra capacity after you've filled the first 4GB. _________________ TT Go Essential |

Mine is a TT920.
To free the internal storage space I first copied the North American map from the TT to a PC, then get a 8Gb SDHC, put the map on it and all my MP3, inserted the card into TT and everything works.
Did it with another 4Gb and 8Gb SDHC card too.
The only problem I found was when connecting a TT to a PC the SDHC card larger than 4Gb is not recognised by the PC due to the internal program of TT, possibly a bug.
In other word if the SDHC card is 4Gb then the PC will see it inside TT and a user is able to do drag and drop with files. If the SDHC card is larger then it has to be read and written externally to the TT using a normal USB card reader. However whatever you write on the SDHC card with a normal USB card reader it can be used once the card is inserted into TT as long as the data is the correct type. I moved the map, MP3 and photos this way.
All the SDHC cards are factory-formatted with fat32 filing system. Reformatting it again with different operating systems or special software do not change the behaviour of TT.
TT930 may have the bug fixed but mine is only TT920. |

The 930 experiences the same issue. No change. _________________ Garmin 1695 / 255 / 760 w/MSN - Droid w/Google nav + Navigon - Navigon 8100T - Dakota10 - GPSMap76C - GeoMate Jr. |

mikealder,
What sort of reliability problem do you have with SDHC card larger than 4Gb? I have experienced any but neither had I used it extensively.
To me once the data is written onto the SDHC and the TT can access it, play MP3, view the photos and use the map that would be all. |

For music it is fine, BUT if a map occupies the space past the 4GB point, or you fill the card with maps when you select a map you can view/ use it. When you try to store POI warnings or any other setting that resides in the CurrentMap.cfg file within the map folder the device fails to write to the card. Minor problem, but from now on until this issue is fixed I will be using 4GB cards instead - they hold quite a large quantity of music - Mike |
