I assumed the AN stood for "Access" as in "Uconnect Access" and "Navigation" respectively.
My unit is an 8.4N ( with navigation and as mentioned, the journey's don't have Uconnect Access/Apps on our uconnect), units without navigation are just 8.4

I've been using my DJ with my iphone for a while now and I know it *worked* before the bluetooth junked out on the uconnect.
(edit: obviously it still works when it's directly plugged in via USB)
As for the "apps", I was referring to on that "A" variant of the 8.4.

I was referring to apps that are a part of uconnect access.

Also, curiously, it says that Sirius XM Traffic is included on the RB5 but I didn't think that feature was ever supported on the 2011?

I can tell you that traffic works on my RB5 - however mine is a second generation (post-2012) radio . . . have you called uConnect support? It may require a firmware upgrade.

Not that it impacts on you, because you are in the US, but I can tell you that Sirius claims traffic isn't offered in Canada. They told me that it is limited to testing only and only to Ford and Mercedes - I had a spirited discussion with them over that. In the end I managed to get them to switch my account to the US organisation and traffic did start working - and it works very well.

I can also tell you that for some reason the Sirius Travelink does not work on radios in Canadian vehicles - we don't get the 'more' icon, even though the radio is identical to that in the US. I suspect that this is a regional feature, enabled by a parameter in the vehicle's BCM . . . . I have the Travelink subscription on my radio - it shows as bring subscribed in the dealer menu, but there is simply no access to the feature.

You need the 8.4 radio unit with or without navigation is up to you, but for the nav to work you need to have SIRIUS already installed on your 4.3 unit otherwise you need to purchase an additional antenna for the GPS signal to work, also you need the touch screen, the dash bezel should be OK.
is all plug and play if you purchase a 2011 unit you don't need an unlock code if you purchase a 2012 or 2013 unit you need to know the VIN number of the donor car.
