Hello, this is my first post in the forum. I've been lurking for a while and need clarification on couple of things.

First of all I have a very old Tomtom ONE XL 4S00.000, please find my current configuration below:

As you can see there are no information about the current map and its version in the ttgo.bif, however I can obtain this information by going to Main screen -> Status summary -> Version:

App 7.130 (8476/070913) OS:2311
29 MB RAM (free: 5.8 MB)
GPS v1.21, Boot 5.3026
Map: 'USA_and_Canada' v710.1575
Language: English US


The first step I've taken was to backup the device which I did. Thanks to that I discovered that the device has 1GB of internal memory. First weird thing I encountered was a painfully slow transfer (it took about 25 minutes to copy 895MB from the device)

What I would like to do with this device is not to mess with internal memory and what's on it. I would like to run it from a 2GB SD card which would enable me to swap between new and old map effortlessly.

Can someone help me by telling me how to proceed with this task step by step?
I know I need information on which Navcore is suitable for this device (what confuses me is that my device has 29MB RAM and none of the Navcores I've seen on this website are less than 32MB. Maybe I got the whole Navcore concept wrong so please guide me through it the first time and I will probably not ask about it again.

Lastly the SD card I have available on hand at this moment is a 2GB card, so this is the size of the map I think I would like to use.

32mb Ram is the memory you have to run applications, same as on your PC.
You need a copy of your current ttgo.bif file on the SD card.
Add widesreen Navcore from here :link:
And a map of your choice from here :link:
You can use a map with automatic installer if you prefer.
The chart in the map thread shows you the features of the map versions, I assume you want a 865.3245 map

Thanks for quick reply Downunder. Few more questions.

Why does my GPS only displays 29MB of RAM? The other unit that I have (Go 720) displays 64 MB of RAM which looks quite normal to me, but the RAM in TT ONE XL bothers me.

Also what is the preferred way of installing Navcore and a map? Do I just install it straight to the SD card, without TomTom even being attached? Or does the card have to be inserted in the GPS?

1. Why does my GPS only displays 29MB of RAM? The other unit that I have (Go 720) displays 64 MB of RAM which looks quite normal to me, but the RAM in TT ONE XL bothers me.

1. This is a question for TT Support.
2. You can install them straight to the SD card. As Downunder mentioned, put a copy of your ONE XL's ttgo.bif file on the card before you run the patcher.

I just updated exactly the same TomTom last week, so here are my thoughts:

1) Most recent navcore: 9.205. Use the automatic installer found elsewhere on this forum, if you prefer. You will need to use a SE Navcore, for the reasons described in 2). I don't believe that this is supported by your current bootloader (please check to confirm) so you'll have to update to a more recent one. Believe that I'm currently running 5.5022.

2) You have a 32MB device, like most earlier TomToms. Later ones have 64MB. This will require you to either use an official navcore & system for this device (8.010 is the most recent) or a later SE navcore.

3) What I did is use the latest official navcore and the latest supported 1GB map on the device flash memory, then installed 9.205 and a 2GB map on an SD card. If the SD card is in the device, it will run the navcore & ttsystem off SD; if there is no SD card in the device, it will run it off internal memory.

1. Every navcore has it's own bootloader included. The correct bootloader for 9.205 is 5.5250.

2. 32MB RAM memory doesn't dictate what navcore can or can't be used.
