So I got back the car without the dealer fixing it. Basically, they have just given up. The car won't connect to InControl Remote. It cannot connect to the mobile internet using the SIM card. And it cannot connect to the internet if I connect it to a WiFi network. The dealer said there us no test that they can do to solve this problem. They keep saying the problem is with the AT&T SIM. I keep telling them no that's not it because InControl Remote is suppose to work without the mobile SIM and it's suppose to be able to connect to the internet once it's latched on to a WiFi connection.
Should I try another dealer? Or is it time to complain to Jaguar corporate customer service?
I think you should try the complaint to corporate and perhaps try another dealer as this software is not I-Pace specific.
I am having the same problem as Epirali where the data connection via SIM is randomly turning off. I am able to turn it back on and works fine.
Also, to your point about Wifi. Even with the SIM removed or the data connection turned off, I can turn on Wifi and the Wifi will work fine. Wifi does not depend upon the AT&T SIM. The user SIM is optional. I think they are confusing the Wifi Hotspot option which requires the SIM. Connecting to a Wifi address is different.
So yes, go back the customer service and see if you can escalate to Jaguar Corporate.
They probably need to start the troubleshooting at the IMC and then work their way to the TCU and then to the portable media interface. I doubt the portable media interface is the problem since you also cannot connect via wifi.
Topix has a very long section on Telematics, but here is the snippet specifically about the Infotainment Master Controller.
INFOTAINMENT MASTER CONTROLLER
The Infotainment Master Controller (IMC) is located behind the instrument panel.
For additional information, refer to:Audio System (415-01 Information and Entertainment System - Vehicles With: InControl Touch Pro, Description and Operation).
The IMC is connected to the Telematics Control Module (TCU) via a BroadR-Reach® Ethernet for data connections such as internet and 'LIVE' data updates
. There is a hard wire connection to the IMC to pass the microphone signal for use by the mobile phone system or voice system. When an Emergency call (eCall) or Breakdown call (bCall) is active this connection to the IMC is disconnected.
The customer service folks should have you go through these other connections. There is a reset process where you can hold down the B (breakdown call button) for about 20 seconds. I can't remember the steps. If they didn't walk you through that yet, they should try. It's an easy reset.
