Hi, I've sucessfully done the steps, but when using the garmin map, it says that the model is not capable to view the Junction View.

Do I need to upgrade to FW again to the most updated version? My current version :

SW Ver 2.70 Nuvi 2W series S3 P2 V7.

The map I used on my 205w (that showed the message) :
typeD.exe 331 041 809 byte
gmapprom.img___102 645 760 byte
gmap3D.img_______1 957 888 byte
gmapDEM.img_____91 275 264 byte
Indonesia.JCV__173 143 109 byte

or should I use the
typeA.exe 133 808 209 byte
gmapprom.img___102 645 760 byte
Indonesia.JCV___67 402 863 byte
? (Will try first..)

EDITED : Apparently I find the cause... It seems that the Indonesian JCV is locked only for Indonesian F/W. if I flash my unit with Indonesian FW, will the JCV, LA, HWM still viewable?

Or is there any way to unlock Indonesian JCV?

That shot is of the exit from the Warringar Freeway to Brook St, in St Leonards NSW. If you have the current AU map and JVC, set your location as north on Warringbar Fwy, Cammeray and simulate a route to Brooks St, St Leonards. You will see that same view as in your post, and maybe the one before too.

The RapidShare link doesn't work, but the MediaFire mirror does, Try again: [Only registered and activated users can see links. ]

If you are getting an on-screen message saying something like "Indonesian Firmware is required ...etc." then you should be able to flash the Indonesian fw to your unit to view the Indonesian JCVs. Do this at your own risk of course. AFAIK, SG/MY fw is the most versatile though. All the asian JCV files are encrypted and can only be unencrypted by their corresponding fw on the device, that is they cannot be unencrypted (ie 'unlocked') by any method to work with other asian fw. US/EU fw units actually crash trying to view any asian JCV file, at least asian units only display the wrong fw message. (Sorry for slow reply, only noticed your post after replying to the post today by www-lisheng).

I'm trying to perform step2 and the updater prompted "There are no USB devices available."
Any idea?
