Hi, I'd like to have routes on my 1390LMT. This thread is 2 years old, but it fits mostly to what I want to do.
Thanks to catymag's link from above, I studied the russian website, their deluxe firmware offers routes and also a lot of things that I don't need like mp3-player, I could buy their firmware, but it needs to be maintained/serviced and webupdater wouldn't work after that. lolypop000 wrote in another thread: "Saniksanik merge SG firmware with US and webupdater dont work with this firmware."



Another option is flashing my 1390LMT - despite it naturally already has JCV+LA+TTS - with: a) 1460 SG firmware or b) 1360/1460 JPN firmware or c) 1690 EU/US/TW/AU/CA firmwares.
The following quotes are from another thread, I'm new and I need 10 posts to post links, but I mean this one: noeman.org followed by /gsm/garmin-tutorials/190929-enable-features-your-nuvi-12xx-13xx-14xx-jcv-la-tts-12.html

1. Which one would be the best for me, a/b/c ? (I would rather keep fullscreen JCV than asian splitscreen JCV, if possible.)
2. When I do this, will I still get my lifetime update from Garmn?



Important for me: I don't want to lose my lifetime map, I like it a lot that webupdater is working and my nuvi is reliable, so I don't want to risk too much and I would prefer not to flash my nuvi if there is another way. In the same thread I mentioned in the last paragraph I found a very interesting quote from lolypop000 21-03-2011, 09:05 PM regarding routes:

Wow, this is interesting! ddabcd277 (moderator) asked lolypop000:

but lolypop000 didn't reply to that question.
I would love to unlock routes by editing something (if it is that easy) with my hex editor after every regular firmware update, so I don't have to flash my nuvi, this seems to be the best way for me. The question is:
3. Using a hex editor (i.e. hexedit mx), in which file should I search and for what string and by which string should I replace it?
@lolypop000 You seem to be THE expert for this, please help!
If someone else knows something, please write, too!



What is the best way for getting the routes option on my 1390LMT keeping the lifetime updates, what do you recommend? Thanks in advance.

@steven-d
In my opinion the delux fw offered by [Only registered and activated users can see links. ] and linked by Caty in the post above yours is the only way to do it entirely safely and satisfactorily. I'm not sure if it's still being developed and/or supported though. He's a mod here, you can send him a PM.

I think cross-flashing to Asian fw or that of any other unit with a different HWID (1690EU/US for instance) is only safe if you use your original boot.bin and you will probably find there are many other downsides anyway that may outweigh having routes.

Hi Neil, thanks a lot!
I will send Alexander2010 a PM,
but before I'd like to wait for other replies (I'm not in a hurry, I think I'll wait until the weekend is over and I do the next step in 2 days on Monday evening; and no offense to you, your answer really helped me),
maybe lolypop000 has now (2 years later) more information about the routes unlocking by hex editor.

You can change PCB number in FW ( decimal) but nothing change, route still don't work.
