Hard Disk

The device comes with an internal 2.5" IDE PATA Hard Disk.

It is Usually an Hitachi Endurastar J4K30 or a Toshiba MK3029GAC with 30GB Capacity.

The disk is divided in 4 Logical Partitions :

Type - FAT (FAT16)
Size - 2.101.572.608=2004MB
Free - Approx 1.584MB
Active partition
This partition holds the Application Software and the TTS (Text-To-Speech) Databases

Type - FAT32 (LBA)
Size - 12.001.810.432=11445MB or 114446MB
Free - Approx 9.187MB
This partition holds the maps Database

Type - FAT (FAT16)
Size - or 1145MB
Free - Approx 1.191MB
This partition holds the user data such as:
- General device configuration
- PhoneBook
- User POI's
- …
It also stores Logging data

Type - FAT32 (LBA)
Size - 14.702.213.120=14021MB or 14026MB
Free - Depends on the quantity of MP3's.
This partition holds the Jukebox Files (MP3 Audio and Playlists)

Hard Drive Backup

It is possible to backup and restore the HDD simply copying all the files in each partition with computer.

Hard Drive Replacement - Notes

Original are special hard drives (to automotion/boat/extreme usage) which offer much better non-operating and an operating shock tolerance than ordinary laptop hard drives. Keep this mind if you gonna replace hard drive. Hard drive capacity has to be at least 30GB.

CD drive is set to "Master", so new hard drive must set to "Slave". The connector inside the RT4 automatically jumpers the original disk to "Slave" by short-circuiting the outer left pins (A+B).


If A+B pins bridge set new hard drive to "Cable Select" or to "Master", RT4 won't boot up. In this case you have cut off pins from hard drive shorter and solvering right one together (if needed) to set new drive to slave.

Hard Drive Replacement - Installing with Software CD

Install RT4 software to new hard drive:

  1. Put new hard drive to RT4 without any partition (at least of 32GB capasity).
  2. Start Engine and keep it running. Otherwise car goes to Economy Mode in few minutes which interrupt installation.
  3. Insert RT4 software CD when in screen read "Please Insert Upgade CD"
  4. Software intallation start and it took 45 min (20 min "Upgrage preparation" + 25 min "Files loading")
  5. RT4 restart itself and system is ready

RT4 software installation creates the correct partitions on the hard drive. If you have previously make backups, you can restore files via computer to new hard drive.

Hard Drive Replacement - Installing without CD (expert/hard way)

If CD drive not work you can restore the partitions from old to hard drive. You need at least restore MBR from original hard drive to new one.

To use new hard-drive than the original one in the RT4, you have to :

  1. Save the MBR of the original hard-drive
  2. Format the new one with the same partitionning as the original one. When using fdisk you have to use the switch -c=dos to create DOS (FAT16 etc.) compatible partitions.
  3. Put in the new disk the saved MBR (with for example the latest version of mbrtool : DIY DataRecovery)

In order to create the partioning manually this information is from an original RT4 harddisk.
No. 1 is "APPLI", no. 2 is "NAV", no. 3 is "USER_DATA", no. 4 is "JBX".
