Review: For older cars, this is a wonderful way to add blue tooth connectivity. - This stupid thing. Seriously. Who needs one of these in 202X? Well, if you have an older car that you couldn't justify upgrading the stereo in, than you do . . . I bought this for an old Saab, and particularly bought this model because it sits more flush than the goose-neck models. My car is a stick, and this is completely out of the way and perfectly sits where I need it. There are a couple things I don't love. One, the lights always default to on. They're easy enough to turn off, but that's the first thing I do every time I plug it in, or start the car: double click the bottom button and disable the LED light show. I know some people may like it, but I find it annoying. The other issue is it can be a little tricky to figure out how to set it up. I've had other models that were a breeze to change the tuning station, but this is a little more finicky and hard to do on the road if you need to. So, for local drives, this is 100% set it and forget it (just double click to turn of the LED each time it starts up), but for longer road trips where you're reaching for the dial to stop station bleed, it's a little more of a pain. Still, nothing I would fault this unit for. It does what it does and in a very small footprint. Sound quality is excellent, especially if you use Radio-Locator.com and the unused station option. On a road trip this is a one-stop-shop for location aware finding of unused channels and a drive from Seattle to LA usually only needs three to four adjustments. Find the right channel (we've always been able to) and it's crystal clear, zero static, and works perfectly. Sure, it's not as easy as having a blue tooth connection to your car's radio, but this is also an item that can be had for a fraction of the price of a stereo upgrade (especially considering installation, any power or wiring changes needed, etc, etc, etc) and it just works, period. If you're looking and wondering if this thing is what you need to be streaming music to your older car's stereo . . . I can say, without a doubt, you'll be happy.
Review: Easy, Simple, Works Great - It's Compatible with my 2012 Dodge. Happy that it works & the bass is great! Even bought some for my family members who have older cars!

### ⭐⭐⭐⭐⭐ For older cars, this is a wonderful way to add blue tooth connectivity.

### ⭐⭐⭐⭐⭐ Easy, Simple, Works Great
*by S***Z on February 26, 2026*

It's Compatible with my 2012 Dodge. Happy that it works & the bass is great! Even bought some for my family members who have older cars!

### ⭐⭐⭐⭐⭐ Works Perfectly//Static fix included in review
*by T***Y on January 30, 2026*

I see people complaining about the static, I completely eliminated the static by not putting the volume on the device at 30, which is the max. I put it on 24 instead, no static. So for example, the volume on my cellphone is maxed out, my radio is at 20, and this device is set at 24. Just flick the analog down to lower the volume to 24. Works perfectly. Easy to setup, and definitely worth the money. If you still have static, try a different FM frequency. Hope this helps.
