I've done some searching in this thread, but didn't find a definitive answer.
Why do you need the antenna adapter? One post said that you need it because without you wouldn't get any stations. Is this true and if so, why.
I have a DNX8120 that I'm thinking of installing which I had in my 350. I just plugged the existing antenna connector into the HU and had no issues.
Does the stock 370 HU have some kind of booster built-in that the 8120 doesn't?
