The most popular thing recently is Bluetooth connection.Pairing smartphones and navigation with Bluetooth, wirelessly transfer and play music data.Bluetooth is simply a wireless communication function similar to WiFi, which exchanges data at short distances.This function is installed as standard from the third -generation mini -3 -door and 5 -door (even if the second generation is a visual boost vehicle, it is possible to play music with Bluetooth).
Until a while ago, the compression of music data performed by Bluetooth connection has become a hot topic when the sound quality is degraded, but now the compression technology has progressed and improved.With a recent Bluetooth connection, the deterioration of the sound quality will be difficult for ordinary people to understand (Bluetooth has a narrow communication area, so the sound may be interrupted due to radio interference).
The disadvantage of Bluetooth is that the battery exhauses fast.For this reason, it is necessary to charge from a cigar socket when using it for a long time (the battery exhaustion level depends on the Bluetooth version and the smartphone setting).
