No AM Radio

[TnK]

Hey all!

I’m trying to troubleshoot my in dash SONY AV Receiver (model XAV-AX3000).
I have not had an opportunity to test all functions on the unit but what I have found is my FM stations are weak and I cannot get even 1 AM station. All I get is static. XM seems to work ok (at least the preview station does), and the Bluetooth for the phone works well.
I have not tried the tv with it.

Anyway…my thought is I need to ensure the antenna is plugged into the head unit. Wherein lies the problem.
HOW do I get to the back of the unit??
Is there a secret to getting the dash apart? Can you go in from the bottom somehow?
OR…Should I just let my (incompetent IMHO) dealer handle that since it is under warranty?

This is on my 2022 Jayco Melbourne L

I have the same RV, Radio and problem. I removed the radio to check the antenna connection. It was connected. So I had the dealer look at it. They confirmed the antenna was connected to the radio so they ordered a new radio. I will keep you posted.
The outer frame of the radio snaps off. I gently used putty knife to snap it forward. Now if I remember correctly there were four screws holding it in place. Then I pulled the radio forward gently.

This sure sounds like the radio antenna position. If the radio turns on, and you hear static on all stations, seems the radio is good, but it has a poor antenna or poor antenna location.

Buy a cheap antenna and plug it into the removed radio (removed from the dash, with wiring intact). Hold the antenna out the door, and see if you can get channels.

I have an older AM/FM antenna from a 67 Camaro that I've tested radios this way with.

***UPDATE***

The dealer has determined the issue is due to a bad antenna (?). They ordered a replacement but JAYCO sent them an antenna for the XM and not the AM/FM.

Now…rather than reorder a proper antenna and/or chase the cable (because the tech is leaning heavily on a bad connector in the existing cable after finding a bad connection at the radio pigtail) the dealer wants to purchase a standard antenna from an auto parts store and install it under my hood.

It would work but…it’s just not right and IMHO he’s avoiding Jerry-rigging my unit just to make it work.

I don’t like the idea so now I need to figure out how to remove the pillar and top windshield trim panels to gain access to the cable and any connectors.
I’m very open to suggestions and recommendations folks (cuz I REALLY don’t like messing around where airbags are concerned).

I would suggest that you disconnect the negative terminal to your chassis battery if you're doing any type of work. After disconnecting, push on the horn to dissipate any leftover charge if any.
