Stereo shuts off

[Tbull]

Ok so here it is I’m stumped, pulled out old unit (some functions wasn’t working) installing a new stereo and it all works until I plug in the antenna and the stereo shuts off. Of course with out the antenna no stations so basically the BT and AUX in but no stations without antenna. Never seen this before read another post about the exact opposite. Tried extra grounds but still shuts off when I plug in antenna. ( even bought new antenna and lead.

The reason the opposite sometimes happens is that HU can find ground through the antenna.  I've never heard of this one.  Is the head unit new?  A reputable brand?

yes it is a new stereo it is a Dual brand model WCP365BT (marine stereo) I'm replacing a stereo in my recently purchased 06 Yamaha rhino side by side. the stereo that was in it was a marine stereo but some of the functions wasn't working.

it is a Dual brand

Might just be a dud.  Those bottom of the barrel brands are known for poor reliability and quality control.

This sounds just so unusual.  Do you have a DMM?  Can you confirm that you still have +12 at the constant and acc power to the head unit after you connect the antenna?
