I understand perfectly what's involved.

I'm saying the WiFi devices in the Jeeps aren't set up the way traditional modems, repeaters and access cards are.

They are merely collectors of WiFi devices that relay the signal to the cellular modem and back again. They don't do anything else as configured.

There are no provisions to connect to a home router. In fact, I would bet there are no settings for things like WEP or WPA passwords which would allow connecting to a secured router, either.

Having said that, it's possible a software upgrade could add that functionality, but FCA/Jeep and UConnect don't see fit to provide those means since they charge a monthly fee AND a daily access fee to connect the way it currently does.

If you understand perfectly then you also understand that that is just software. Once you have a packet driver, which you need to have to do any packet I/O then the rest is just a question of how you use the network stack.

It is possible, though unlikely, that the bunch of retards that wrote the software for Chrysler actually wrote their own network stack. Given that it works OK that is highly improbable.

Right now inside the tiny PoS (you could call that Point of Service but that's not what I call it) computer in your dash the network is configured with an external address on the cellular interface and an unroutable subnet gateway address (like 10.0.0.1) on the WiFi radio. The PoS will be running NAT and DHCP to hand out addresses to things logged in to the gateway and then convert them to look like they came from the cellular PoS itself. Returning traffic is converted to the original address.

So what needs to change? Switch off the cellular interface, stop NAT, stop the DHCP server, reconfigure the WiFi interface to be a DHCP client, switch to the home WiFi channel and network. Login.

Since the radios actually receive all packets on their frequency, yes I know it is direct sequence spread spectrum, you can actually work several SSIDs at once if you have the right software. So the stretch goal would be talking to WiFi at the same time as still serving the hotspot. It's just net to net routing. Every home gateway can do it and does when it hooks a WiFi connected device, like a laptop, to a wired device, like the printer or receiver.

if you hack it, it comes with the drivers for some wires usb devices and you can then apparently get a bsh shell that way.

might not actually be that many steps away...

see this thread below, it gets way over my head, but seems the folks posting there have hacked even the later versions and have gotten as far as futzing with the firewall (which apparently wasn't set right even now....)

uConnect 15.26.1 is buggy; I want to downgrade.

Re: 2014 Grand Cherokee Map Update

I believe it's the map update I bought last May ('15).
Item #: U3562-0060-504
This one is Part number U3562-0060-509
My guess it's the same update.

It would be nice if we could verify this. I'm leaving on a trip in about three weeks and would like to have the latest update if this is new.

I would assume that's the date the update package was created, not the date of the maps.

I think it's probably safe to assume we won't see updated maps into either Q4 of this year or Q1 of next year. Those maps will likely reflect being up to date through Q2 of this year, based on results from previous data.

Re: 2014 Grand Cherokee Map Update

What I hate about the NAV system is that I will plan out a trip on my PC using either Bing Maps, Google Maps or Mapquest then when I put in the destination to my NAV it almost always takes me a different way than any of the 3 would and if you are not familiar with the area, you are not positive that it is telling you the correct way to go. On a recent trip it would've had me go WAY out of my way had I not known the route beforehand. There should be a way to look up the route that the NAV will use on a PC before you go to plan the trip.

Re: 2014 Grand Cherokee Map Update

Ive noticed that on mine, granted i'm still running the 2012 maps. There is an area where i live where a hwy is getting expanded and my normal hwy ramp is closed off so when i plug in the address on nav it still makes me go to that ramp and then reroutes me. I've already learned to not go that way and find an alternate ramp but its annoying.

Another thing too, sometimes when traffic begins to slow down it'll re-route me which i assume is because of the traffic congestion?

So i hope we can get an exact date of the maps for sale on HERE to make my decision to buy now or wait it out till the next one. Just this weekend i used the uconnect app to send address to vehicle for a new venue and nav took my to an incorrect place. Luckily my destination was not too far off (10 miles away) and had to use my phones gps to find it.

Re: 2014 Grand Cherokee Map Update

I was on a trip once and it tried to reroute me because of traffic congestion, etc. I wasn't in a hurry so I stayed on the regular route and turned out there was no sign of any problem. When I got home I looked up how it wanted to reroute me and it would have taken me WAY out of my way!

I would be interested in seeing a screen shot of the "upgrade" USB file directory/structure.
