LordMetro, just to give my 2cents even though I have a 595 with the 7" VP2 Radio which you can find in the current 500L as well. My system is NAVless but has Android Auto / Carplay and I was checking the engineering mode and at the Positioning menu I found out that I have fully functioning GPS capabilities. Upon checking the Misc tab I found that it comes loaded with TomTom Software v14800.2538775.8101 but missing the maps. Because I work at a dealership in Portugal I had the chance to dump the DEVLOG information from a unit with NAV and compare it to my NAVless:
This is what I found under HW Variant:
NAV: HW Variant = 0xCDA24E71 DAB eMMC GPS S&S USB BT LS CAN 1GB NAND MIC1 dMIC 9V PhtSupl DT FP
NAVLESS: HW Variant = 0xCDA24F61 DAB GPS S&S MOST USB BT LS CAN 1GB NAND MIC1 dMIC 9V PhtSupl DT FP
So the NAVLESS lacks the eMMC which should be the partition/place where the maps would be located but has additional MOST support (maybe something to do with Carplay?).
Maybe the eMMC Rom is physically there maybe it's just a software bypass or not... I guess the only way to find out would be to change the HW Variant code and perform a FW update to see if it would stick and show up the NAV icon (the maps and license would be easy to get from a MapCare enabled vehicle from linkentry). So I had a look at the vehicle proxi dump and found a "Nav Presence" marker which reads 0x1 for the Nav Enabled and 0x0 for the NAVless and also a GPS Presence which reads 0x1 for both. Could it be as easy as enabling the Nav Presence via WiTech in the CAN settings? I am not familiar with the WiTech UI as I am on sales.

Yep that might be the case with the swap.
I was just explaining how the uConnect installer updates. There's only two actual software platforms, for us lot without the navigation we get their 'dummy' software. Installing the tom-tom software will be useless without a GPS antenna, also buying their maps without the GPS functionality is a waste of money too in my opinion.
I just use the tomtom navigation app on my tablet and have a magnetic holder above this uConnect device. I have heard TomTom are looking to discontinue map updates for their older devices and I assume this could mean our uConnect too? So installing another uConnect unit with the navigation wouldn't be cost effective either. The newer uConnect seems to run a similar UI to the newer navigation models they produce. This will need further clarification with them.
