Harman Kardon Internet Radio Not Working — Restore vTuner
An empty Internet Radio list or “No stations”
A server or connection error when opening Internet Radio
If your Harman Kardon AVR shows an empty Internet Radio list or a server error, the directory it relied on (vTuner) became unavailable on many older receivers. Retune·FM gives Internet Radio a working address again.
Build your own station list
Harman Kardon’s Internet Radio directory went offline for legacy AVRs
Internet Radio on these Harman Kardon receivers was powered by vTuner. When vTuner turned its directory into a paid, restricted service, many AVR models could no longer load the station list — so the menu returns an error or comes up empty. Retune·FM answers where vTuner used to, and the list fills up again.
This applies to the network-capable Harman Kardon AVR models that had a vTuner-based Internet Radio menu. Newer models on a different streaming platform don’t need it.
一项 DNS 设置，大约两分钟
您只需在 Harman Kardon 上更改一个值——它的 DNS 服务器。网络上的其他一切都不会改变。
| Harman Kardon | Remote Home → Settings → Network Settings → set IP Mode = Manual/Static → note and re-enter IP address, subnet mask and gateway → set the DNS to 62.132.3.28 → save, then open Internet Radio. |

以下是此方法通常能够恢复的功放。如果您的型号曾使用旧的 vTuner Internet Radio 菜单，应该可以使用——不确定？开始免费试用，没有任何损失。

确认电台已恢复
将 Harman Kardon 关机再开机（或重新连接网络），然后打开 Internet Radio / NET RADIO。列表应会重新活跃起来。如果仍为空，请再次检查 DNS 值，并确认功放从路由器获取其设置。
Harman Kardon 用户常问
Which Harman Kardon models does this help?
The network-capable AVR models that used the vTuner Internet Radio menu — the AVR 151/161/170 generation and the AVR 3770, among others. If Internet Radio worked before and now shows an error or an empty list, this method applies.
这合法吗？需要应用程序吗？
Yes, and no app. Retune·FM only links to publicly available radio streams and is not affiliated with Harman Kardon or vTuner. You change one DNS value on the receiver — no app, no account.
如何撤销？
Set the receiver’s DNS back to automatic (or your router’s address). Everything returns to how it was.
