Want Bluetooth audio and handsfree calling in your older car? This Wirecutter-recommended dongle takes the Bluetooth signal from your phone, and retransmits it to the FM radio station of your choice. The sound quality will take a hit, but if you don’t have an AUX jack, this is probably your best option short of buying an entirely new stereo.

We’ve seen deals on a few similar products before, but this one can actually pair with two separately phones simultaneously, if you want to trade off DJ duties with your travel companion. [GOgroove FlexSMART X2 Bluetooth In-Car FM Transmitter, $30 with code X2SAVE10]
