Having this issue as well and wanted to chime in..

According to Reddit Carplay also uses compass information which may be off:
Does anyone know how to re-calibrate the compass on the E?

Unfortunately driving under 32kmh for ~5 minutes with the car navigation app in the foreground did not fix anything for me :( I tried this multiple times over the last few weeks.
Strangely there was a period of a few days where it worked well, and it always seems to have an accurate location at the start of the trip, and then losing accuracy a few minutes / ~1km in, perhaps as Carplay tries to switch from phone gps data to the car gps?

When the issue occurs, I think it is something to do with the compass as mentioned. When it starts to go wrong, I notice that the arrow on the map tends to be pointing off at a tangent to the actual direction of travel on the road (should be pointing straight ahead).

I suspect that perhaps the car does not have a compass (but does have GPS), and relies on the phone sensor. Perhaps the phone sensor is being affected by the large electric currents between the battery and the motor , and after a while android auto just goes 'This data doesn't make any sense anymore'. It is hit and miss, most times it's OK, but occasionally it will start to lag behind and then get stuck - normally only a few minutes after use. Perhaps the phone orientation makes a difference too?

When it works, it works for the whole journey (aside from the normal connection/starting issue which is almost certainly a Xiaomi specific issue).

I’m wondering if it’s a general phone issue and nothing related to the car.
My reasoning behind this is because on a recent drive from Newcastle to the South coast in another car (not our Honda e) both my iPhone and my son’s Nothing Phone lost the GPS signal a couple of times and zoomed off the route at so we had no idea of which direction to take at the next junction.

I agree. I always assumed that the car's GPS was not used anyway, if you are using CarPlay, because aren't you running the apps all from your phone then? If you use the car's on-board Garmin navigation, I would assume it would use the car's GPS, but if you use your phone apps, I would think it would use the phone's GPS.

I did have a localisation problem for a little while, until I realised I hadn't given proper location permission to the navigation app in my phone (Android though). I had set it to "Allow location use while using the app", but it stopped updating the location as soon as I put the phone away or close the protective lid. I had to set it to "Allow location use all the time" to get the navigation app to function properly again.

The problem appears to be specifically related to the Honda E and Apple CarPlay. We've tested Android Auto and the integrated Nav in the car and both work fine. The problem seems to be related to all Navigation apps running on an iPhone, such as google maps, Apple Maps, Waze Tom Tom, CoPilot, etc. We tested wired vs wireless, different iPhones, different cables, different iPhone settings and different Honda E's and all exhibited the same problem. Interestingly, other Honda cars, such as the Jazz, HR-V and CR-V don't have the same problem. The problem seems to be worse in some parts of the UK than others and I'm suspicious it could be something to do with the antenna. I've reported it to the Honda Customer Escalation team, who were very dismissive and told me to let Apple know they have a problem and if I wasn't happy, to talk to the Motor Ombudsman, which I intend to do.

This thread appears to be the most appropriate, so how about deleting your other posts and continue on only this one, that way people might be more inclined to provide advice or their experiences.
