Updating GPS firmware is risky if you don't mastered the procedure.
You should also know burn the CD or DVD properly on quality support.
If in doubt, buy or done install the update by your dealer.

It's best to go from one firmware to another in order.
It may happen that there is a mistake if we directly update from oldest to newest.
550 to 552 is better !

Hello Bricoman, thanks for share this firmwares !

Can you help me ?
I don't know much about this material, but I know you need the same FW from your unit 663b890 CD to change the language of the RT3.
You can also go to see your dealer, he can do the job with the suitcase.

You can do it with .iso file, just burm a CD 4x, watch the video.
Both files are disk images, .cue and .iso

Verbatim CD is the best, never error, 4x is quite enough to burn it !
