[General Accessories] fisely:
Freezing up of software resolved - see below

After contacting TomTom Suppo :D rt I managed to get further info and advice which I followed and this has resolved the locking up of the software - works brilliantly now.

Dear TomTom Support,

Many thanks for your last response. I am pleased to report that after purchasing a SD Card with a speed of 80x (Read of minimum 12mb/second), as per your advice, and reloading the GB Maps - everything is working very well without any freezing and locking up of the software on my XDA IIi.

I would advocate a note be included, in future, with TomTom products on guidance about Storage Cards and using ones with appropriate speeds for reading/writing etc. for the benefit of other potential users of your products.

If I had knowledge on this subject prior to purchase of SD Cards, I believe, I would have bought one with appropriate speeds.

Once again thank you for resolving the problem.

Dear Mr hussain,

The process of elimination would suggest that the SD card is causing the freezing issue, the software seemed to work when the SD card was taken out of the equation so it would suggest that the read speed of the SD card is causing the problem.

Dear TomTom,

Many thanks for your last response.

Can I deduce from the message that if I purchase a branded (and more expensive) SD Card with a Reading speed of at least 10MB/Second and load up the maps for GB - it will then work without locking and freezing up?

Best wishes

Faisal

Dear Mr hussain,

When using SD cards, please bear in mind that the reading speed should be at least 10MB/second, because the map data continuously will be read from the card. The card writing speed is not important in this sense, because the application is not going to write on the card as for instance would be the case with a digital camera. Please also bear in mind that the writing speed specification “45x speed” means that the reading – respectively writing speed of the card is 45x150Kb/s and that is why it is only 6,75 MB/sec (60x speed means 60x150Kb/s and this is 9,00 MB/sec.). Please ask your reseller for more information about whether the speed indication is about reading or writing speed of the card.

Regarding the SD cards in general, we have received numerous reports.

Many cheaply made SD cards, most especially those SD cards without a brand name, can cause problems regarding reading speeds or in a worse case scenario have corrupted files on the SD card and are therefore not readable. Cheaply made SD cards may also have a weak memory controller on the card, which although these cards might work fine in a digital camera, may not be able to pass information quickly from its memory to the TomTom GO application. This can for instance result in freezing of the TomTom application or poor map redrawing. Another issue could occur during start-up: If the map exceeds a certain amount of data, it can be that the GO application is not even going to fully start-up.

We hope to have answered your question to your satisfaction.
