What is it?

Btconsole allows you to login to your Tomtom via a serial port and a terminal emulation via bluetooth connections.

• The advantage is that you don't have to patch your hardware, just a chunk of software is required.
• The disadvantage compared to a hardware solution is that you get access to a fully booted Tomtom but cannot see the boot process itself. After all, you connect via the network.

How to do it?

I've had some difficulty with the provided documentation, so I give some hints here.

Tasks on Tomtom

• Install btconsole on your Tomtom Go. (homepage is http://btconsole.renevoegeli.de/ )
• Start btconsole on Tomtom.

Tasks on Windows

• Download a Bluetooth-stack that supports the needed protocol, like Bluesoleil
• Establish a serial connection to your TomTom
• Use a serial terminal like HyperTerminal to gain access to the console

You can even up-/download stuff using lsz/lrz and HyperTerminal.

Tasks on Linux

One of the following:

1. Boot your favorite Linux distribution.
2. If you are unsure, just download Knoppix, a Linux distribution that can fully operate from CD without installation and that contains the necessary tools.

• Login as root
• Make sure you have /dev/rfcomm0. If not, create it like this:

mknod /dev/rfcomm0 c 216 0
chmod 666 /dev/rfcomm0
depmod -a

• Scan for your Tomtom device to find out the bluetooth address.

hcitool scan

• Connect your serial port to Tomtom

rfcomm bind /dev/rfcomm0 00:13:44:7b:39:65

• Start minicom to access Tomtom.

minicom

• You will have to tell minicom which serial port to access.

Press Ctrl-A O
Select Serial Port Setup and press Enter
Press A (Serial Device)
Enter '/dev/rfcomm0' and press Enter (to assign the value)
Press Enter (to leave the menu)
Select Exit and press Enter (to leave the menu)

• Press some keys until you see the tomtom lofgin prompt
• Login as root (no passwd required)

Tasks on Mac OS X

• Pair with the Bluetooth device
  • Launch Bluetooth Setup Assistant, from
    • the Bluetooth menu (Set up BlueTooth device...) or
    • System Preferences / Bluetooth / Devices (Set Up New Device...)
  • Select Any device as the device type, and click Continue
  • After a while, TomTom will appear in the devices box, identified as a Computer
  • Click Passkey Options..., and select Do not use a passkey with this device, and click OK.
  • Select the TomTom and click Continue
  • Click Continue again once the gathering additional information is complete.
  • Click Quit.
• Add the device to favourites if not already there
  • Launch System Preferences / Bluetooth / Devices (if not launched already)
  • If TomTom does not appear in the Devices box, try to Browse it (from BlueTooth menu), and add it to Favourites from Bluetooth File Exchange
  • The TomTom should now appear in the Bluetooth Devices box in the Bluetooth preferences
• Add a serial port
  • Select TomTom from the Bluetooth Devices box
  • Click Edit Serial Ports...
  • After a short while, the port appears in the dialogue box. Click Apply.
• Connect
  • Launch terminal
  • Make sure the device is there:

$ ls -l /dev/tty.TomTom-SerialPort-1
crw-rw-rw-   1 root  wheel   10,  22 Feb 22 15:55 /dev/tty.TomTom-SerialPort-1

• • Install kermit if not installed already:

sudo port install kermit

• • Launch Bluetooth console on TomTom
  • Use kermit to connect:

$ kermit -l /dev/tty.TomTom-SerialPort-1 -b  9600 -c

• • Type a few returns; you should get the prompt:

TomTom login: 

• • Enter "root", no password is required.
  • Welcome to TomTom root shell:

BusyBox v1.00 (2006.01.17-14:38+0000) Built-in shell (ash)
