Fix for Incorrect SOC in Apple Maps

[snstevens]

I'm using Apple Maps via wireless CarPlay to handle routing for EV charging. Generally it works well, but once in a while I get a warning that the SOC in Apple Maps may no longer match the true SOC in the Taycan.

In the past I've corrected this by deleting the Taycan from Apple Maps on your iPhone, and then opening the My Porsche app, going to Details, Functions, and Apple Maps EV Charging to re-connect. However, the last two times I tried this, these steps resulted in a blank page in Apple Maps, and no connection.

I tried a number of things including the 2-Finger PCM reset, closing both the Apple Maps app, and the My Porsche App, but nothing worked. What did work however, was the following --

1. Open Apple Maps on your iPhone.
2. Click on your picture (typically a head shot) to the right of the "Search Maps" bar.
3. Click on Vehicles
4. Click on your Taycan entry.
5. Scroll to bottom and click "Remove this Vehicle"
6. Open the "My Porsche" app on your iPhone, click on "Details", "Functions", "Apple Maps EV Routing", and click on "Open Apple Maps".
7. If Step 6 leaves you on a blank page in Apple Maps, shut down the Apple Maps app (swipe up from the dock on your iPhone), and do a hard reset on the iPhone.
8. Open Apple Maps, then open My Porsche and re-establish EV Routing clicking "Details", "Functions", "Apple Maps EV Routing", and click on "Open Apple Maps". This time it should connect correctly.

If anyone finds a better way to fix the mismatch SOC problem, please let me know. In the meantime, I hope this is helpful.

Note - I run the latest iOS version (17.1.1 at this time), and I just recently had the WPN9 PCM Update applied. There is likely a bug somewhere in either iOS, My Porsche (Version 9.1.0), that is the cause. My bet is iOS since the reset fixes things.
