Newbie Go930T Firmware / Internal Memory Management Query

Greetings folks.

Many thanks to all who have posted here and provided invaluable info.

Just recently bought Go930T and have the following query(s)

1. Having backed up the internal memory straight out of the box (via explorer) can the whole internal memory be wiped at any stage, reformatted and the original files copied back to the device....will this work? I had thought i read somewhere about problems people were having and reformatting was a solution....Am worried that wiping all the internal files and folders will prevent the device from connecting to the PC to reinstall files via explorer.
2. I havent yet upgraded the firmware from 8.002 to 8.302 (bit scared to) if I do which files / folders are changed?
3. Similarly when I take up the Latest Map Guarantee (in about 2 wks time) does it only replace the files in the 2 map folders (EU & NA)? Thus allowing me to back them up and replace in the future.
4. Will 4GB SDHC cards work under firmware 8.002 / 8.010? also what is the maximum normal SD card size that these firmware versions support. I know that 8.3 and above support 8GB SDHC and higher.

Appreciate any help you can give me

Thanx

1. The computer would just see the unit as a drive with no data on it. Yes, you can -- if necessary -- restore a complete backup to a reformatted unit.
(and you've done a good thing by using Explorer for your backup instead of Home).

2. Normally, it is the loose files in the root of the unit, not any folders or their contents, that get replaced. Don't be reluctant to update to 8.302.

3. Yep, the new maps will overwrite the old ones and it is an **excellent** idea to do another backup (to a new folder) once all that updating is done.

4. You can use a 4-gig sdhc card with that application and you can go even higher but, in order to do so, the process gets convoluted since TomTom would only write to the 4 gig but could read from more than 4 gigs. Life is much easier with 8.302. TomTom will read/write to even 32 gigs with no problems.

I suggest you go ahead and update to version 8.302. Judging from the lack of posts about voice problems etc, it seems that it has cured the problems that the earlier versions were having. Also, when you update your maps, they won't work without the latest application, and you'll be able to use any size SDHC card that is currently available. I'm using 16gb, with about 10gb of mp3s on it.

I have used both 8GB and 16GB class 6 SDHC cards in my 930 with no issues, they are manufactured by Peak - Mike

if u were going to format the internal memory before copying back an explorer backup, do u format it FAT32?

is that ok with the TT's Operating System.

Sorry dont have mine with me to look and see if it iit is FAT32 already....

MY 940 internal memory is FAT32.

I ended up returning the TT930T i bought last week. Maplin had it on offer for £200 and it included the £70 CD for 2 year updates.....thought this was a bit of a bargain, so saved £40 and got the free 2 year updates, plus a photo album offer which looks good for consolidating some holiday snaps.

So, what I am thinking is, connect the new one tonight to my PC for first time and do full explorer backup, just in case there is any difference between the files of the one I returned (think it is same firmware version 8.002).

Then I was going to get my firmware update (v 8.302) and use latest map guarantees to get totally up to date....followed swiftly by another backup!!!!

But before I did the updates, i was thinking of doing a full format of the internal memory.....(full as opposed to quick format) as i read somewhere that a sector by sector format is the best way to ensure your device's internal memory performs correctly....any truth in this?

cheers

I would say "don't"
You DEFINITELY need to make a new backup of the new device, as the map certificates will be specific to this unit.

So, backup, update, backup again, yes. But no need to format.

I must have altered the contents of my TomToms hundreds of times and have never needed to format except in very rare circumstances (the internal memory on my 720 has died and failed progressively over a couple of weeks.
