[Android General] limited_imagination:
What you are looking for is the "Notifications" volume slider, and if you crank it up, then the TomTom voice guidance will be louder than the music from the Asteroid Smart media player app. If you go into the main "Settings" app of the Asteroid Smart, you can adjust volume sliders for different types of sounds, and you're looking for the one marked "Notifications".

As long as I am logged in here and discussing Tomtom 1.4 for the Asteroid Smart, I will post a mod that allows it to give sound and visual warnings for fixed radar camera locations.

It works perfectly if you follow the instructions posted by uzak27 here, in respect of the old Tomtom 1.1 for Android app: http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=146319&whichpage=1

You have to follow the sequence of starting and closing the Tomtom app precisely as those instructions state, for it to work. Note the "default.inf" file added at step 16 is only added after the app has been run and then closed, with the other modified files.

I am in North America, so I could not just copy the file content that the Europeans used in that thread. I have Tomtom US & Canada, Version 1.4 (1733195), Map: US & Canada v935.5817. This version was my last update of Tomtom as provided by Parrot, before they removed all support for the Tomtom app and pulled it from the Asteroid Market.

So here are the changes that I made for this map, which seems to work perfectly.

The file folder used by my Asteroid Smart for Tomtom is: sdcard/.extra_content/com.tomtom.uscanada/tomtom/com.tomtom.uscanada/files/USA_Canada/

Apparently Tomtom periodically issues a new encrypted OV2 file containing the GPS coordinates of fixed radar cameras for their various maps. But you only receive those if you subscribe to their additional data service. I don't think that Asteroid Smart users were ever offered that service on the Asteroid Market, and even if they were, it must be unsupported by now.

So you will have to create your own new OV2 file, if you want this feature. There are various open source POI lists of radar cameras available if you hunt for them, that you can use to create your own unencrypted OV2 file. I found that the Windows program GPSBabel was really helpful for this task, because it can convert from something common like a GPX file into Tomtom's proprietary OV2 format: https://www.gpsbabel.org/

So I created a new "OV2" file in the Asteroid Smart Tomtom folder, and named it "Safety_Cam_US_Canada_TomTom.ov2"

I created another new file in that folder called "Safety_Cam_US_Canada_TomTomOv2.ver", with the following content:

My "default.ver" file now has the identical content to "Safety_Cam_US_Canada_TomTomOv2.ver", as per the forum instructions.

I created a new BMP image file called "Safety_Cam_US_Canada_TomTom.BMP", with a 44x44 pixel image of a radar camera, that I snagged from a Google search.

I created a new OGG sound file for an alarm, and saved it as "Safety_Cam_US_Canada_TomTom.ogg". I also saved that very same file as the filename "default.ogg", as suggested by "Acapulco" on page 4 of that thread, so now I have two identical OGG files with different file names: http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=146319&whichpage=4

That should do it.

Note that you only get the visual & audio warning if you have entered a destination into Tomtom. The app needs to be navigating to a destination where the radar camera falls along the route, in order to warn you. The warning pops up at 550 meters from the radar camera and it counts down distance from there.

Interestingly, you can mute the turn-by-turn instructions in the Tomtom settings, but you will still get the alarm sound at 550 meters from the camera. Even if you are playing the radio app in focus with Tomtom running in the background, the radar alarm still sounds out at 550 meters from the camera. If you mute the radio app, the Tomtom alarm still sounds out at 550 meters from the camera.

Make sure your "Notifications" volume slider is high enough that the alarm sound is louder than the radio...
