I'm using a Joying Chinese head unit in my car since a few months. I did not order HD-Traffic yet as I was testing another app with free HD-Traffic, coupled with the fact that I don't like AT ALL that navigator changes my route without informing me. (I don't care about 13 minutes delay at 1½ hours drive away from me. By the time I'm there it is most probably solved, so I want to decide myself).
Anyway, these Joying units get regular firmware upgrades. However, on every upgrade both the device-id and the MAC-address is changed. Don't ask me why, as it really stupefies me as well.
I know from other users, trying to use Navigator with HD-Traffic on the same brand, but also other brands, that this happens to them as well. Thereby making HD-Traffic not workable. It is somehow bound to those Chinese ROM/firmware builder companies.
I don't want to discuss whether the (in this case stupid) Chinese units should not change device id and MAC-address, but how can Navigator with HD-Traffic work on this?
Why is the license coupled to device-id anyway? Why is it not coupled to your Play Store account like the "Premium options" and like many other purchases I did outside Navigator on the Play Store.
To me this is a No-Go for Navigator (in combination with the rerouting behavior), in favor of that other app. Even though I prefer the functionality and excellent performance of Navigator over the other slower app.
Is Mapfactor going to change this licensing model?
licensing model is determined by our agreement with TomTom, premium features are not part of that I assume your device has SIM, so you should not have problem when device ID changes
My device doesn't have a SIM in case you mean a SIM-card. In the most simple representation you can consider it a tablet attached to "radio hardware", with "interface apks" to the underlying hardware being an amplifier, an AM/FM chip, (possibly) DAB+ hardware, etc.
Note also that I refer to other users having exact this problem, and that that's the reason I did not yet purchase a license. I'm not talking about what could happen. I'm referring to issues users have because of this. I try to prevent to get there.
