Hello everyone,
Newbie here, so apologies in advance for my lack of knowledge and stupidity!
I have a Zumo 590, Branded as "Harley-Davidson Roadtech". It turns out, unknown to me when I bought it, that it's a Dealer Demo version. That means no pre-installed maps (and thus no lifetime updates) and only 4GB RAM (Garmin's own 590 has 16GB, standard HD version has 8GB.)
I want to use the whole of Western Europe region maps, and as 4GB isn't big enough, I guess that means a GMAPSUPP.IMG on an SD Card?
Assuming I'm right, does that method give me junction view, 3-D buildings and terrain?
Now, I do have an ordinary Garmin Zumo 590 (firmware upgraded to 595) with lifetime upgrades, and using "UnLock MapSource.exe" I seem to be able to unlock the maps for that when they are installed to the computer. Using Mapinstall before they are unlocked shows nothing available for the RT Zumo, but after running the unlock program, the maps are shown as available. However, the 4GB RAM on the RT Zumo is not enough to install to the device. Mapinstall allows me to install to an SD Card, but only recognises it as 4GB too, regardless of its actual size (16GB). That's another problem I guess I need to solve.....
I tested though, buy choosing a small region. However, the RT Zumo still shows "Cannot unlock maps" when it boots. That makes me think I also need patched firmware for it? I've looked at that thread, but there seems to be no listing for a Zumo 590 - presumably because the ordinary ones come with lifetime maps!
A little more complicated too, because I do want to also upgrade the RT Zumo 590's firmware to the ordinary Zumo's 595 (I know that can be done) because I need the TPMS feature which is not included on the RT 590.
So, please can someone point a stupid newbie in the right direction?
From GarminDevice.xml, as it is currently:
<Model>
<PartNumber>006-B1796-00</PartNumber>
<SoftwareVersion>330</SoftwareVersion>
<Description>zūmo 590</Description>
And as I expect it to be with the 595 firmware upgrade (assuming the PartNumber doesn't change):
<Model>
<PartNumber>006-B1796-00</PartNumber>
<SoftwareVersion>460</SoftwareVersion>
<Description>Zumo 590</Description>
Thanks!
