I agree with the previous comment completely. With a relatively old car, my new phone was no longer compatible with the Bluetooth equipping the original vehicle. Incidentally, this Bluetooth incompatibility is outrageous, since the standard states that the protocol is backward compatible with version 2 to version 4. In reality, it is the associated software, especially those of Android, a completely despise any backward compatibility. That is why I Asteroïd with a Mini, and as regards telephony, the goal is more than achieved, since I enjoy in addition to voice recognition, which greatly facilitates calls received or issued. Of course, I did not have this facility with the original system. In addition, the multimedia audio quality is good, or better than original with his equalizer with multiple settings. That's why I put one more star than my predecessor. For the rest, I found some bugs. For example, if we arrange the music in separate folders according to the artists, all is well as long as you do not cut the ignition. But if we take the road after a stop time, the screen of the ASTEROID will display only the time, without even switching on the radio and it will search the music we listened before stopping. Furthermore, applications are downloaded only from the device, which may cause Internet connection costs via the smartphone. No way to download them from a PC via an SD card, contrary to what is stated in the instructions for the device. Gros also disadvantage of not being able to act on the volume if you exit the application that plays music. Overall, this is a very powerful device given its size, with a very well studied remote. It is perfect as regards telephony and audio quality. By cons, it is confusing by some bugs and software design not quite developed. Hopefully updates will correct these deficiencies.
