## Questions & Answers

**Q: What does it say when you plug it in and what does it say when you connect a phone ? Sounds like it's in Chinese ??**
A: Hi,Here is the answer I got from the seller that I did test and work to change back to English from Chinese:"Hi,As for the issue that can't get the Bluetooth to sync with phone,wondering can you try remove all the blutooth device on your phone and re-connect it again?And for the isut that it changed to Chinese, can you try remove the Bluetooth connection by shutting off the phone. The volume knob should be blinking, indicating 'Bluetooth Unconnected'. Hold the volume knob down for five seconds, then release. Remove power from the device by switching the ignition key off (Note: If 12V is still present at the accessory outlet, you will need to unplug the device). Reapply power to the device. The message voice should be toggled to English if it was previously in Chinese (or vice versa)."I found out why my Nulaxy was not pairing due to not compatible with HUaWei Smart Watch.  When my smart watch is connected I have to go to the BT menu and manually pair to connect it.

**Q: can you leave this plugged in or will it drain battery?**
A: It depends on the car, for example, my 2003 Ford Taurus will power the unit after the car is off (draining the battery), but my 2014 Toyota Camry won't power it when the car is off. A good way to test if it will drain your battery is to plug a phone charger and see if it charges with the car off and key removed. If it does, it will drain your battery, if it doesn't charge, then it won't.

**Q: my car is an old car, so it does not have an usb adapter or a aux connector, would this work on my car anyway?**
A: Yes, as long as it has a cigarette lighter 12 volt outlet  .... it plugs in.  Then simply find a station that has nothing playing on the radio and then set your transmitter to that same station.  You can play songs off your phone, stream IHeart radio or Pandora by using blu-tooth or simply use a 3.5mm audio connector cord .... it plugs into the transmitter and your older MP3 players headphone jack.

**Q: my car does not have aux out put....will it work?**
A: I think you mean aux input. But, the short answer is yes. like the other 2 mention, this can work off of radio waves. The there is a 3.5 mm headphone jack (basically your farily standard headphone jack on *most* devices) on this device so you 'can' use almost any form of item with a 3.5 mm Jack such as a 3.5 mm Jack to cassette adapter if your car still has a tape deck. But, you can use the fm function too if you want. Like nulaxy explains, the transmitter does 87.5 fm to 108.0 fm, but you'll want it to be on a clear frequency. I often just use 88.1 fm due to the fact that I know for the most part, most radio stations won't be transmitting on that frequency, unless it's a drive in movie theater or a certain special event or something like that. If you've got a working cigarette lighter port, often called theses days as a 12 volt power port in your vehicle, it should work.
