Thread: Add JCV/Lane assist to nuvi 205w - Any new guides?

Maybe it is time for update of used SW:

Yup, fair comment Giomen. But before posting the guide for imgr i converted an old [1GB] 255 with AU logo to 465 using that rgn file and Updater.exe initially gave that error but flashed properly on the 2nd attempt. I've since downloaded kunix's modded RGN_Tool but haven't tested it [i don't need to, we both know it will work anyway, right? ].

Normal rgn tool must work with no problem on this device if all is created properly.

Try with this from PouchX

Spoiler: 2x5W to 465

Do you have .rgn in the same folder than Updater.exe?

@imgr
I think maybe you've made something wrong. I used the file shown in post #6 to flash an old 255 and as i reported in post #10, succeeded on 2nd attempt. Did you also try with the older firmware in PouchX file posted by Loly above? It doesn't include the logo.bin, or you can try with the 4.60 fw without the logo initially and then flash the logo later if successful.

The PouchX file 082701000321.rgn is the same combination of firmware as 082701000420.rgn [2x5W boot.bin and 465 fw_all.bin, w/o the logo of course] but contains earlier versions of firmware modified by PouchX. It's known to work, it's very safe and it's a little smaller than the later firmware version combo which may help with the loading.

You would still need to flash the 465 logo to enable TTS i think, unless your 205W has previously been flashed with the senior 2x5W logo to enable TTS. That can be done later anyway if needed, so baby steps ... try either of the files without the logo.bin initially.

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.
