I will soon be buying a new ds card for my RAC SatNav 100 so that I have bigger memory and can download speedcam database and more poi's. The current sd card is FAT32 format, should I format me new card as FAT32, or will it operate better formated as NTFS?

Tks

Steve

Leave it as it comes. If you do want to reformat it then use Panasonic SDFormatter, a free download.

If you are going to get a new, bigger SD card, get a "FAST READ", or whatever its called. When I bought my bigger card, I bought a normal one, and when the speed camera icons are displayed, and the alerts are on, the sat nav runs slow, it says "TAKE THE NEXT TURNING ON THE RIGHT", JUST AS i HAVE GONE PAST THE TURNING, so I have to turn the icons off and just have the audible alerts on. When I get round to it, I will copy my SD card again onto a faster card.

It doesn't matter whether you use FAT16 or FAT32 on an SD card. What may matter, depending upon how you use the card, is the cluster size. A few years ago when using TomTom 3 on an iPaq I found that larger cluster sizes dramatically improved the performance of the application. To-day, with more, larger and faster SD cards, I either format a card in the device in which it will be used, or use SDFormatter which formats it according to agreed SD card standards.

You may end up being slightly disappointed. The 'high speed' cards are generally high speed for writing, which is not required for this sort of application. The read speed may well be faster than the early cards but not by a huge factor. Most PDA's (and all-in-one satnav systems) have an internal transfer rate below what most cards can support. What you are probably seeing is the affect of having a large number of POIs visible - along with the proximity detection. This takes quite a bit of processing power.

After doing quick search on internet, It would appear that some cards may not accept Fat32 some will. and from a personal experience I upgraded from a standard 2gb to a unknown x133 2gb card on my Mio168 and did find it was better and slightly quicker specifically it stopped Sharon Stuttering, perhaps reducing POIs may have helped also who knows, Probably case of "you pays your money then see"

NTFS is only really for file security on your drive (card), so unless you have your card networked 8O FAT'll be fine.

Once again

Tks for all you help

I think I will get a 2gb card with a speed of x133. I will carefully choose my poi's that are shown on the map/alerts.

I will use the spare space to download some mp3's as the unit is capab;e of playing them.

Correction! I just got suspicious about my own memory, so I searched the old messages. It was actually TT2 and, contrary to expectations, the smaller cluster sizes gave quicker performance. YMMV.

I bought a sandisk extreme 3 card from my memory and it loads visibly quicker than the tom tom stock card.

The Sandisk is one of the cards I have looked at, think that's what I'll buy when I find a good price - must check 'pricerunner'.
