I can confirm that the Laredo version of the Uconnect system (8.4A VP3 ROW) does
have the hardware required for navigation.
It simply needs the activation code entered in via the dealer menu.
Aussie dealers will charge far too much for this ($2K) but the same upgrade is available online from US companies. Most dealers here (oz) have a 3rd party do this for them such as Doyle's for example, so not getting it from Jeep is not really an issue.
Following a long debacle with Doyle's and my dealer, during which time they upgraded my unit incorrectly with Nth American software and numerous other updates, only to fail to get it to work at every turn.
They tested the GPS receiver in the unit but couldn't get a signal, so rather then coming to the logical conclusion that there was a hardware issue, they wasted my time for 6 mths trying everything except testing it on a different unit or just doing a warranty claim.
Eventually I got in touch with a US company whom, from my detailed record of events, immediately suggested the Sierra wireless module was faulty. Now the dealer is going to replace the system. They also confirmed that the dealer/doyle's should not have updated the software (particularly with a US update) as this is not required.
I intend to get my $2K refunded once the Uconnect is replaced and then get the NAV activation code via email for $500 USD. As is the case in getting it done via the dealer, all that's required is the VIN, and request code as noted in the previous posts. job done.
