First of all, I'd like to thank you Catymag and Neil, especially if you are positive that HWID is 1187.

I didn't buy nuvi 2350; I got it from friend who had found it in car (he works for used car dealership and that car came from auction). When I started device it showed "nuvi 2350", something about Telstra (forgot what exactly was written) and installed map (it was an old map, which I replaced with latest one - CN NZAU HERE 2016.10).

Yes, I know 2350 hasn't BT chip (I've read manual) and that's why I was surprised finding BT icon in the menu. Since this nuvi had an old map (2013) I doubt that previous owner had a knowledge how to mod it. I found features here: System\Diag\html\supported_features.html

The only two *,gcd files (006B125700.gcd whith date 01/11/2012 and 006B090100.GCD 02/06/2013) I found here: System\RemoteSW\*.*

Ok, it was very confusing described by me. I did "clean users data" (it's not really important why I did it) and when nuvi started it asked me to enter 4 digit PIN. Since I didn't know it I started from 0000 and 5486 unlocked my Garmin. I wrote down that number and wanted to change PIN but Garmin Lock menu just don't exist (Tools/Settings/System/Garmin Lock). After a couple days I did "clean users data" once more counting I know PIN (5486) but it didn't unlock my garmin so I started again from scratch and unlocked device with 1150??? If the PIN hasn't been randomly changed I really don't know what's happened.

@Neil
It's obvious that I don't know how to find HWID. Reading tread I was thinking that the only way to find HWID is dragging gcd file into RGN_Tool. As a result I got HWID N/A. If exists another way to find HWID, please tell me. Without it I can't do neither NV backup nor enabling fitures.

Thanks in advance
