thanks Andy , does the transfer speed matter ? the cheap ones are about 4mb/s or is that the class 6 thing you are talking about?

Yes, the "class" is just a unified way to describe the general speed of the card (different manufacturers used to use different methods to measure the speed (or you might say - "cheat"!)

There's a little chart here (Plus more info than you could ever want...)

last question andy , currys have PNY micro sd card at a good price , are they any good?

PNY is an OK brand and has been in the business for quite some time.

As for the previous "Class 6 or better" comment ... Class 6 seems to be the sweet spot for these devices. They are slowed slightly by use of a Class 4, but don't seem to benefit from a Class 10. So it's really a matter of what you can find in at least a Class 6 for a price.

I didn't see the "ST" serial called a 'World' model, but it indeed is an 8GB version with full maps, and a microSD card slot. TomTom released a whole bunch of units and called them 1005, so knowing the first two digits of the serial number is about the only way to keep their specific features straight.
