FM radio signal after EntryNav upgrade from CHAMP2

Suprnowa · 06-10-2020, 08:35 PM

I upgraded my CHAMP2 HU to an EntryNav HU.

It's been worth every penny, however one item which hasn't worked as well since the upgrade is the FM radio.

The new EntryNav has two FM inputs, whereas my old CHAMP2 only had the one.
Any ideas how to resolve this?

I also did this operation. The main task is to make a jumper between the two fm outputs, or buy a y-shaped wire

Very bad idea. Splitting the signal will at the very least cut the signal in half. You end up with worse reception than before.

No, it helps, tested on dozens of cars

You cannot change physics.

If you want to retrofit the entire diversity system, that’s a different concept with 2 antennas. No splitting signal strength.
