Listening To Music In My Car Without AUX port or Bluetooth?

I have a 2006 Nissan Murano, it doesn't have an AUX port or a option for Bluetooth, iPhone's have an apply to broadcast music thru a radio station and I wanna if there's an app for that on the galaxy s5 or a little device that could go where a phone charger would go and be able to play music from my phone to a radio station, there's a device like that but only plays with a micro SD car

I have tried the iPod to FM radio gadget (not an app.) and it doesn't work very well; lots of dropouts and hiss. Best way is to burn your compressed music files onto data CDs and play those disks. I can fit several hundred songs onto each disk by saving them as MP3 format, not just an audio CD (74 minutes maximum).

No app will do that. You need hardware, an actual device, an FM transmitter, it connects to your phones headphone jack and transmits the audio via FM frequency. No iPhones have a built in FM transmitter, they still require a separate transmitter.

If your factory radio have a working cassette player, then you also have an option to use a Cassette adaptor, this is better than the FM transmitter in my opinion and does not require any battery power.

Stay away from FM modulators or Transmitters, they don't sound good, lots of static and noise, nothing wireless is going to sound good,

The good news is that you can buy an auxiliary audio input adapter for Nissan Murano radios, this audio input interface connects to the back of the radio using the satellite port
