Evelyn ★★★★★ Oct 19, 2026

I was a bit skeptical at first, but this adapter fit perfectly into my Nissan's factory harness and the radio lock-in improved noticeably.

Nicholas G. ★★★★★ Oct 18, 2026

Plugged this in and the diversity function works perfectly with my aftermarket radio, no signal loss at all. Took maybe two minutes to install.

I was worried about losing the diversity function when I swapped in my new head unit, but this adapter kept it working perfectly. The plug fits the factory antenna socket on my Nissan with a nice firm click, no wiggle at all.
