Thread: if i update nuvi 3590 to version 8.30 by garmin wepudater ??

There is no GSV protection in 35xx firmware so the firmware doesn't require patching. There is Map Signature Verification (MSV) protection in the firmware however so a map unlocker that doesn't overcome MSV in the required map won't work. Read the first several posts in [Only registered and activated users can see links. ] for the full explanation.

Which maps are you trying to use with ASR? Some countries don't have ASR files available for the maps and some won't work with partial maps and need the entire available mapping to be loaded, i.e. US/CA and Europe. More info on that here: [Only registered and activated users can see links. ].

I should rather word it differently:
There is no MSV protection in 35xx firmware so the firmware doesn't require patching. There is GСD Signature Verification (GSV) protection in the firmware but it does not matter in this case, because the firmware doesn't require patching.
To unlock a map you enough to use the old gimgunlock-0.03 (without MapSigPatch) or one of its derivative.

hello
The voice command icon does not appear in the app section at all
any idea
i mean that the icon itself r not there
when i hard reset i choosed Egypt

Choosing a locale does sometimes enable or disable certain features in particular devices. Two examples I've encountered are Audible Exceed Speed Limit Warning and Auto Zoom. If there are no specific ASR files available for Egypt mapping from Garmin, then perhaps choosingمصر [Egypt] as the Locale disables ASR completely, even removing the Voice Command Icon. I'm guessing however.
