Android Auto: map rendering corruption and delayed/frozen GPS position in ABRP 7.1.7 (5980)

Hello ABRP Support,

I am experiencing two serious and recurring problems with ABRP when using Android Auto in my Volkswagen ID.4.

I am currently using ABRP version 7.1.7 (build 5980).

The problems are:

1. Map rendering corruption

During navigation, the standard ABRP map sometimes becomes badly corrupted. Large rectangular areas of the map are rendered incorrectly, almost like corrupted textures or image blocks.

The important point is that the rest of the ABRP interface remains correctly rendered. The route line, vehicle position marker, turn instructions, speed limit, arrival information and vehicle/SOC information remain visible and sharp.

After some time, the map may recover by itself and display normally again.

I am using the standard ABRP map, not satellite view.

I have attached photos showing the corrupted map and a normal map from the same trip.

2. Very slow or delayed GPS position

Especially after starting Android Auto, ABRP can take a long time before it determines the correct vehicle position.

The same problem can also occur later during a trip. ABRP may remain behind the actual vehicle position for a significant amount of time.

This is particularly problematic in cities or other areas where several turns occur close together, because the displayed position and turn guidance can become too late to be useful.

Test conditions

I have tested this with several different Android phones.

I have also tested both:

• wired Android Auto via USB

• wireless Android Auto

The same problems occur in both cases.

Google Maps does not show the same GPS or navigation problems on the same phones and in the same car.

This makes it unlikely that the problem is caused by the phone GPS hardware, USB cable or the vehicle's infotainment system.

The car is a Volkswagen ID.4.

ABRP also appears to continue receiving vehicle data correctly while the map problem occurs. For example, SOC information is still displayed.

ABRP version

Build 5980

Summary

There appear to be two possibly related Android Auto problems:

• corruption of the standard map rendering

• delayed or temporarily frozen vehicle/GPS position

Both problems have occurred with several different Android phones and with both wired and wireless Android Auto.

I would be happy to provide additional logs, screenshots, phone models, Android versions or perform specific tests if that would help you diagnose the problem.

I previously tried to contact ABRP regarding this issue but did not receive a response, so I hope this more detailed report helps identify the problem.
