How to add Bluetooth to a Retro, Non-touch stereo on a student's budget

I am hesitant to spend my savings on modifying the Chevy as it's old and wont be used much. The main criteria for all this is that I don't have to spend too moolah on the car

Here's what BHPian d.w.w. replied:

Almost 14 years back my ex-colleague came up with the exact same problem. And the solution he found was an aux(3.5mm jack) to Bluetooth adapter; the 3.5mm jack will go in to the aux port of the stereo and the phone will connect to the BT receiver. These adapters should be pretty cheap now.

Meanwhile here's what BHPian saket77 had to suggest in this matter:

You need something like a a car FM transmitter. It fits to the 12V cigarette lighter socket and you just got to tune your OE stereo to the preselected FM frequency. The FM transmitter device (eg: https://www.amazon.in/Ambrane-Transm...zcF9hdGY&psc=1)
can connect to bluetooth & you can play through an SD card or USB flashdrive- all by your OE stereo. It is also good alternative for handsfree BT calling and works very well. I have used 2 of these and both worked well. The only small drawback is that the bass drops a little during the transmission.

Like mentioned above, I got one of these for my wife's Alto K10 where she wasn't a big audiophile and just needed the basic requirement of connecting her phone to the audio system to take calls and play music seamlessly.

We used this - https://amzn.in/d/dbXQ3E6 which worked brilliantly well and will highly recommend it.
