Bought one last time on sale over the summer and it is now dead and it's only dec. Didn't even last 6 months! It overheats within 2 minutes now and then shuts down completely then turns on again and the cycle continues. Buy a different brand. I just got a different brand yesterday to replace this one.

I have 3 different brands in my other 3 cars and all have lasted and are still going strong 5-10 years later fyi

Probably. I got one of these precisely for that reason and it works fairly well. It's definitely worth this price.

Got this to replace a bulkier one for my car, only to find out this one makes a high pitched whining noise that varies with my engine RPM that my old one didn't.

Yes. I have a similar one in a 2005 Toyota van and it works pretty well. It even has a built-in mic so I can make phone calls over the speakers.

How do you set these things up? Can I make it work with my car speakers, or does it need to use the speakers (what looks like speakers) built in?

And is this for taking calls, basically? Or what else do you get it to do?

Any suggestions for units that don't make this sound (coil whine)?

The one I got unfortunately came with my car when I bought it used. However, it looks very similar to this brand being sold on Amazon, albeit mine is older: https://www.amazon.com/Nulaxy-Wir...B018E0I01I

you know you can buy a BT receiver (head unit) for your car for $20. way better quality than an FM transmitter.
