Cheap and easy Bluetooth

I have an am/fm/cd with a remote mounted under my passenger seat and was wanting Bluetooth without replacing my head unit. I looked into sending my dash unit out to one of those companies that do the retro mod but the price and hassle of shipping it ended that. Started searching the interweb and found a 12 volt plug in FM transmitter for $12. It also has 2 outlets for USB charging AND has a voltage readout. You will need to sync it with an unused FM frequency and pair to your phone. Once you do that it will pair automatically. I use mine for Spotify (not phone calls) because radio is so lame these days. I like it so much I am using one on my motorcycle and in my 09 Ram. The only down side is that it will drain the battery so you must unplug it (cigarette lighter) when you park the car but you could always wire up a key on outlet. Check it out.

Sounds like a simple fix to an old problem. Would have been a good idea for the GTX - I’ll pass it along to the new owner. Thx

Just a heads up, I tried one of these in a '67 Belvedere and a '99 Viper. In both cases, I got a whining sound from the ignition. The noise got louder as the RPM's went up. It worked fine in my Ford Focus work beater though.

Never been a fan of those fm transmitters.

I've tried several over the decades.

Was excited when they finally moved to digital tuning but that didn't really seem to help.

Not enough transmitting power, station drift and bad interference.

YY1....Maybe I got lucky but I have 2 different models with no issues. On my bike I have it in my saddlebag with the factory HD head unit in the dash. Rode 250 miles from N.Y. to NH and worked great. Key is in choosing an unused station frequency.

When adding electronics that reproduces audio into any year car, you can get what is known as "alternator Whine". What you are hearing is the actual electrical output of the alternator varying with RPM's. The alternator generates an AC voltage that is rectified into a rough rather nasty looking DC voltage. The cars battery acts to absorb or smooth much of this nastiness but not all of it. The solution is a proper filter in the 12 VDC power lead to whatever you are adding to the car. One such filter is here :
