TT750 map update to card

RichardM · Lifetime Member Joined: Jun 13, 2005 Posts: 138

I have a TT750 which I want to put the latest map of W&C, Europe Turkey & Russia on. I have a 4gb sd card which has a copy of the original backup on it. When I connect to Home with the card in the TT750 it is recognised and I have the choice of which memory to use. Because I had a problem with Home writing to the wrong memory, I want to use a card reader with the SD card in it. However when I connect the reader to Home it does not recognise it despite the fact that I can see it in My Computer. What am I doing wrong? Any help appreciated.

I'm not sure but I think the application also needs to be on the card.

Thanks for the reply. What do you mean by "the application needs to be on the card"? The back up which is on the card should contain everything that was on the internal memory, so should be identical to the original.

Sorry, misread your original post. Thought only the maps were on the card.

Is it a fairly modern card reader? It should work in the card reader (and is it a fast card? - class 6?).

It's probably an HDSD card that you are trying to read in a non-HDSD card reader. Only recent computers are capable of reading HDSD cards in their built in card reader. You probably need an HDSD card adapter to plug into your computer.

Yes I have a Kingston card reader now and this is OK with sdhc cards, and it is a class 6 card that I am using. The card shows up on My Computer and I can read the contents. For some reason Home will see the card when it is in the TT but not when it is in the card reader. I realise I should be able to download the maps while it is in the TT but last time I tried Home decide to use the internal memory instead of the card so messed everything up. Hence the reason to want to use a card reader. How do I get Home to recognise the card when it is in the reader?
Thanks

Have you tried formatting the card and copying the original backup to it again?

You don't have the TT plugged into the PC at the same time as the reader?? (The card won't necessariuly show up as a TT drive, sometimes just as an external drive - how many external/USB drives have you got?)

I have tried with TT and reader connected at the same time and by itself. I have two spare USB connections. The reader shows up as a multiple drive on My Computer but when connected by itself Home says there are no devices connected, but when the card is in the TT it shows both memories and gives you the choice about which drive to select.
The reader and the card are both working OK as shown by being able to access the card contents via My computer, it is something to do with Home. Either I have somehow got something wrong or missing from the card which is preventing Home from seeing.it. I have checked both memories and and the internal one has 1.76 GB used and 149 mb free and the card has 1.77GB used and 2GB free. There are the same number of folders on both so I can't see what is missing. The only difference is the used capacity with the card being a bit more.

I had a reply from TT support and they said that "Home will only recognise a card if it is inserted in the unit. This is not a fault but the way the software is built." This is despite it saying in Home help that once a card has been initialised it can be read in a reader. Though there is a footnote to that which says "Memory cards used with GO x20, x30 or x40 navigation devices are not intended to be used separately in a card reader. Hence if you access one of these cards through HOME in a card reader, HOME will not recognise the card." Maybe they have not updated the Home help to include the x50 models.
Has anyone used a card in a reader with a x50 model or any of these other models?
I have emailed them back asking for clarification of these contradictory statements and they say they will ring me if I arrange a time with them. So I will see what happens.

I've just done it to test for you with the 2GB SD card from my 520. I used to do it with an 8GB SDHC card from the 520 too (until I found a better use for 8GB).

Right now, Home offered me update to Navcore 8.351 (not flamin' likely thank you!), QuickGPSFix (same again) and phone settings. It long ago gave up in disgust trying to get me to accept MapShare corrections and simply tells me my map is out of date and there are 2,000 unused map corrections which I really should take!

So you have proved it works on x20 models. Anyone prove the other models work before I speak to TT.
