First time poster, long time reader..
I just installed the 2011 map update on my AVIC-Z120BT and I am getting a System Error about the tuner, that will not go away.. The problem is that I am on a long road trip and I need the use of the nav, and the error blocks the screen
I have talked to Pioneer and they informed me that the MSN Direct tuner needs to be taken out because it no longer works with the new update...
I didn't install the system myself, and was wondering how hard it would be to disconnect on my own.... Any help would be very much appreciated. Thanks in advance!

To do it the right way, you will need to get to the back of your HU. The car's antenna is daisy-chanined through the MSN Direct tuner. That is, the antenna plugs in to the MSN tuner ANT In, then another coax goes from the MSN tuner to the back of the HU. Then there is a harness that connects the MSN tuner to the HU. This also powers the MSN tuner. That will need to be disconnected from either the HU or the MSN tuner (or both).
You might be able to disable the MSN tuner without removing the HU if you can reach it from under the dash. You could just unplug the harness connector. Going this route, I'm not sure if you will loose AM/FM reception. It is possible that the MSN tuner has a passive bypass of the antenna lead. If so, the antenna signal will just pass through the MSN tuner even if it has no power. So your AM/FM will still work. Even if it doesn't, this should eliminate the error that keeps you from accessing the NAV.
Hope you follow what I'm saying. I think the hardest part to do on the road would be getting to the back of the units. Can't help you there. Each vehicle is different.
