Editor's Overview

Qz is a navigation application developed by Michael von Glasow, packaged as a single Android APK of version 2.1 weighing in at 20.87 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 20.87 MB, so it installs quickly even on modest connections.
  3. This build is signed by "Michael von Glasow" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Receive live traffic news via Traffic Message Channel (TMC)

Qz (pronounced “queues”) connects to an RDS/TMC receiver to receive live traffic messages. TMC is transmitted in the RDS data stream of various radio channels and provides live traffic information, helping you avoid congestions.

For a list of countries in which this app can be used, see https://gitlab.com/mvglasow/qz/wikis/countries.

In order to use this app, you will need a supported RDS/TMC receiver. The following devices are currently supported:

* GNS FM9-BT (requires Bluetooth)
* Silicon Labs Si4701/4703-based USB tuners (requires USB OTG support)

If you are unable to pick up any traffic messages, despite having a supported device and being in an area which should be supported, check your antenna. Reception with pigtail antennas (a long piece of wire coming out of the receiver) is generally poor and insufficient for TMC. It is recommended to rely on your vehicle antenna, a building antenna or a somewhat decent room antenna.

Qz will only work with unencrypted TMC services (as encrypted services require paying a per-device royalty). Also, some countries have chosen to require paying a royalty for access to their location tables (which Qz needs to decode TMC locations) and are therefore not supported.

Frequently Asked Questions

Is Qz free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Qz require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Qz safe to install?
We link to the exact APK published by Michael von Glasow. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Qz?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
