Problem Bluetooth car renault

I do not know if it's just here to talk about this problem, anything I'm sorry.

Well, when I sync via bluetooth my iPhone 5S in car nav media Renalt Sendero, only from what I understand the car's computer can not handle the transfer range that spotify allows moving the settings realized that the minimum that is permido is 96 kbps, is there any way to lower the quality more so I can test whether this same problem?
