    The unit should now show 'nuvi 465' in small white print instead of 'nuvi 205W' at the base of the boot screen. You can check the fw version a few ways: From main screen - Tools>Settings>System>About. From main screen - Hold battery symbol for ~5-6 seconds to enter hidden menu>Next>Start Test>More then look at top of page, 3rd line will show the version after 'System B0827-00'. Finally, connect to PC and look at the GarminDevice.xml in a web browser [found in the unit's Garmin folder]. The fw version also shows in there, this is from the conversion i did the other day to v4.20 on the old 1GB nuvi255 AU version:

    You need to load a TTS voice. The logo you've added is for senior 2x5W which will enable the street name announcement but that function requires specific voice files. Connect to WebUpdater and they should now be offered. Don't upgrade the firmware with that method or it will flash on boot back to 2x5W. After you connect to PC, but before starting WU, using NotePad edit the xml file by changing the 3 numbers following <SoftwareVersion> to 760. i.e. so it has this: <SoftwareVersion>760</SoftwareVersion>. That will allow you to go to Voice etc files without WU wanting to update the fw.

    No need to change the xml file back after you've updated, the unit will re-write it correctly on reboot anyway.

    BTW, never flash the full 465 firmware to your unit. That will change the hwid from 0827 to 0943 and increase the chance of it being permanently bricked immensely.

    Ahhh no ... Looks like it has not updated. Still says 205w everywhere.

    So i re-did the update again. I saw something interesting. It said "Loading Loader" > Loader > Software Loading and the unit restarted. It said Nuvi 465 at the bottom and then PouchX. I was happy momentarily. Then again it said "Loading Loader" > Loader > Software Loading and unit restarted and back to 205w. So I end up with 205w again. Looks like my unit has some restriction or locked firmware which cannot be updated.
