TomTom 3 Can't work out a long route without hanging

[murmur]

I use 3.07 on a Mitac Mio and tomtom does not seem to be able to handle any journey that is in the slightest bit complicated.

If I put a longish journey into the "itinerary" or "navigate to" it works it out fine, then the timer starts spinning as it's about to show the map, then it just hangs.

If I then go to display the full map, it quits.

The wierd thing is as it's hanging, it will give me the voice instructions and guide me all the way but I see no map just that infuriating timer going round. This is also no good if I want to do an alternative route or avoid a road.

I have taken off checkpoint and disabled all points of interest to run it bare bones but nothing seems to work.

Any ideas?

I have not had this problem myself but I am wondering if it could be due to a slow or poor quality memory card. A fast SD card can make a huge difference to route calculation times over a standard SD card and some of the poorer cards (made in China printed on the back) are known historically to have had problems with them (see http://sdprob.aximsite.com/theproblemlist.htm for more detail).

Good luck

murmur - post the markings on the back of your SD card. That may help to tie down the problem.


longwori - I find the information on Jon (Happycheesecake)'s site increasingly less useful. Things have moved on since the days of that site - for a start, there were only something like three companies making SD cards then.

Recent Sandisk SD cards seem OK, even though I have a long memory and tend to buy other brands. I've got a standard (blue) Sandisk 1GB SD card that was given to me for test purposes (BB0411WH - which means it was made in November 2004 and is "W" technology code) - and I can't break it with the tests I've tried. If I feel particularly brave, I'll swap it over with the Lexar 32x 1GB SD card that usually lives in my hx4700.


The troublesome SD cards tend to be those that aren't marked much. In particular, there's some cards with a letter followed by eleven numbers in tiny print on the back; my experience is that all those cards are bad!

There's also a "MADE IN TAIWAN" SD card that's been mentioned a few times in the forums as being troublesome.


One thing that's worth trying is reformatting the card as something like FAT32 with 2KByte clusters, then copying the maps onto the card before any other data (which should stop them fragmenting).
