Just want to add that I'm not the author of this mod, nor is the guy who shared it on the BG forum. Even though I believe I understand what this does, I will not be able to help in case something goes wrong, so apply this at your risk. What I can confirm is that it worked for me and my car description is in my signature.
This should work on R-Link 2 versions 2.2.19.30x, 3.3.16.94x, 3.3.16.96x and 7.0.24.13x.
If you have something else then best to first upgrade (downgrade?) to one of the supported versions. I personally have 3.3.16.96x (upgraded from 2.2.19.300).
It's a two step procedure - step 1 is installing software update file (linked below) that will modify the iGO (navigation) partition of the R-Link, allowing for unsigned / unlicensed maps to be installed later. Then step 2 is installing the maps themselves.
Step 1:
From the list below download the update file that corresponds to your R-Link software version:
mm2014_upgrade_igo_2.2.19.300_gz.zip (igo 9.12.80.689874)
mm2014_upgrade_igo_3.3.16.940_gz.zip (igo 9.12.133.675708)
mm2014_upgrade_igo_3.3.16.960_gz.zip (igo 9.12.133.696450)
mm2014_upgrade_igo_7.0.24.130_gz.zip (igo 9.12.138.703531)
Extract the file to a FAT32 formatted USB stick and plug it in to R-Link - its similar to how the v2 -> v3 update happened but quite faster (as the file is smaller) - you get a bunch of yellow lines and then R-Link reboots. Note that the navigation part of R-Link
will reset at this point, so you will lose any settings / favorites / POI locations etc.
At this point you have a modified iGO partition, which basically looks exactly the same as stock, only difference is that it now accepts unsigned & unlicensed Maps updates.
For step 2 you need a Map file to install. The file is similar to what Renault provides via the R-Link store - a .SKU file that contains the map. Only difference is that this file is not licensed and you can prepare it yourself (although its not that trivial to do).
The post on the BG forum includes .SKU map file for Eastern Europe - Here Q3 2018 Balkan region 526MB (Albania, BosniaHrz, Bulgaria, Croatia , Cyprus, FYROM, Greece, Kosovo, Montenegro, Romania, Serbia, Slovenia, Turkey) - here's a
link to that
. You extract this to a USB stick (in the R-LINK folder), stick it in, then you'll see the prompt for map update and the rest is on the screenshots from my previous post.
I'll also translate the instructions for how to build the SKU file (so you can make one for UK or other parts of Europe or the world) - this is definitely for a separate post or even thread.
