Got my radio back on the water
My dog chewed through the original mic cord on my MR F45-D. This CA 345 B plugged right in and everything works like it did new. transmit and receive are both perfect.

Exact OEM replacement
Ordered this after the original mic on my F45-D stopped keying up. It arrived in Cobra packaging, plugged into the front connector, and worked instantly. Channel up/down buttons are responsive, the backlight matches, and the waterproofing seal looks identical to stock. Saved me from buying a whole new radio. Very pleased.

Good backup mic
Bought as a spare for my F45-D since mic failure is the most common issue with these radios. Tested it at the dock and it keys up fine with clear audio. Slightly stiffer cord than original but no functional difference.

Works but buttons feel mushy
The mic functions correctly on my MR F45-D and transmits clearly. My only complaint is the channel buttons feel a bit mushy compared to the original. For the price it's acceptable.

Salt air couldn't kill it yet
Two seasons in the salt on my center console and this replacement mic still keys up crisp every time. The original lasted about the same length, so that's just the marine environment, not the mic. Fits my F45-D perfectly and the contacts haven't corroded. Will buy another when needed.

Saved a whole radio
Cheaper to buy this mic than a new VHF radio and that's a win in my book. Plugged in, worked instantly, audio reports are strong. Only docked a star because shipping took a few days longer than expected.

Second one had to be returned
The first mic arrived and wouldn't key up at all on my F45-D. The replacement they sent works fine, so I think I just got a lemon. Customer service made it right quickly, which is why it's not one star, but check yours right away.

Reliable replacement
No surprises here. It's a genuine Cobra mic that restores full function to the F45-D. Coiled cord has good reach from the dash to the helm seat. Would recommend to anyone with a dead mic.
