This Xiaomi Roidmi 3S cigarette-lighter-sized Bluetooth transmitter and car charger has two USB outputs totalling 2.4 amps output AND is able to talk via Bluetooth to your mobile phone so that those without Bluetooth on the car radio can tune into a special low power FM transmission and play their phone music via the car stereo. Not only that but it is inexpensive! The unit came from GearBest – here’s the link…
Xiaomi ROIDMI 3S Bluetooth Music Car Charger: https://goo.gl/uzmHh6
Thr Roidmi website is out of date, featuring models 2 and 2s whereas the unit I have is model 3S. Operation requires little explanation so really the GearBest link above is good enough. Once the unit is paired to your phone by Bluetooth, all sound output from your phone or tablet will go to the unit and be retransmitted by radio (FM) to the car radio. The unit also of course has 2 USB charging outputs which can be used for example to charge your device or devices - always handy in the car.
The Roidmi 3S is solid enough, if you are unfortunate enough not to have Bluetooth on your car stereo, it could prove useful. The brief instructions (which I didn’t need) were in English. It has now been in use for weeks in our little Spanish car and operates flawlessly.
I must admit to being sceptical at first, I’ve seen similar units over the years promising to send music over FM and usually ending up with disastrous sound. This unit on the other hand has true, clear stereo and sounds GREAT with no interference from other stations, at least, not here in the Granada region of Southern Spain. My UK car has full Bluetooth but our little Spanish run-around has no Bluetooth and as the radio stations are Spanish, has, up to now been essentially useless.
Now, we can stream my wife's favourite American Rock station from her Smartphone to the radio andeven keep the phone charged at the same time – marvellous.
