Hi All

I want to buy a big SD card for my Dell X50v to install TOMTOM.
The card is only used in PDA.

In ebay you have the flowing choices.

Sandisk 2G SD card (OEM) ---£45
Sandisk 2GB Ultra® II Secure Digital SD™ Card (OEM)---£65
Sandisk 2GB Ultra® II Secure Digital SD™ Card ---£80

Is it really worth to buy the expensive one to get tomtom run faster??

thanks

Check the fastest speed your unit will operate and choose the card which matches.

In my case Mio stated 133x so I went for the Kingston Ultimate.

Tom Tom should be running OK on a normal card as mine does so just use a normal 256mb's card just for TT5.

I only ever use a 1gb fast card for photos mp3's etc on my PDA.

I use the "cheap" 2g SD card from 7dayshop.......on my x51v, with TTN5.21 with no problems.....

Erm, reluctant to disagree with maca2 on this as he's given some really good advice loads of times. But here goes.

From my own experience, since using the 512MB High Speed card, the blue arrow on screen shows me actually passing a turning when I'm doing so, with my previous card, Kingston 1 Gig Standard, it always showed slightly behind where I was. Also the voice indication, turn right or left, at a T junction, now comes several yards ahead of the junction instead of at it.

thanks for the help from Lost_Property,maca2 and mburton2.

It looks that the card's read speed is more important to tomtom.

Found some test result in aximsite.

"
SanDisk Ultra II 1Gb SD Card
Read Speed: 0.92 MB/sec / 6.3X
Write Speed: 0.02 MB/sec / 0.1X

KingstonTechnology 256MB SD Card Card 1
Read Speed: 1.17 MB/sec / 8.0X
Write Speed: 0.01 MB/sec / 0.1X

KingstonTechnology 256MB SD Card Card 2
Read Speed: 1.15 MB/sec / 7.9X
Write Speed: 0.01 MB/sec / 0.1X
"

I think I will go for a Kingston 2GB card instead of Sandisk.

Just because the Kingston 256MB card was fast, it doesn't follow that the 2GB one will be!!
I prefer to ensure that TomTom is tracking my position as closely as possible. I therefore confine myself to 512MB cards, and have several for covering diferent countries. They are pretty cheap and it's very little trouble to change cards occasionally. I work on the assumption that as TomTom would have to read through so much more data on a 2GB card, it must be slower

a very good post was found about the sd/cf card used in PDA

http://www.aximsite.com/boards/showthread.php?t=99097

The result is surprise!!!!

A-Data 50x 2G SD card is the fastest card at the moment.
If it is the case, this is the card for tomtom.

Am I right???

Don't know if this is relevant for a DellX50V but I was running TT navigator 5.21 on my O2 XDAIIi (running WM 2003) with a SANDISK UltraII 1GB (66X) SD card and it ran fine except for using the traffic updates via the GPRS connection when it constantly froze during downloading the data, probably 4 times out of 5. It was very frustrating.

Tomtom suggested using a minimum 80X card so bought a Kingmax 2GB (122X). I can't say I noticed Tomtom running any faster or better with the faster, higher capacity card, but it certainly improved the traffic downloading. Now only freezes 1 time out of 5, so still not perfect. Windows media also freezes less when playing MP3s.

I subsequently found that by disconnecting and reconnecting the card after tomtom traffic had frozen, it continued to download the data and then carried on without having to carry out a soft reset.

So I don't think a faster or bigger card made tomtom run better but it certainly improved the traffic downloading.

Hope this is useful.
