I have a 05 TL Automatic, non nav. I installed the PXAMG back in January, stuck with the .36 firmware that came with it. I am having some issues with it periodically and I am not sure what is actually common, what is not common and what is unrelated. Hopefully you guys can either clear some of this up or make me think I am less crazy.

Issues:
1. When listening to ipod, sometimes will display No Ipod Connected and the song will cut out. Normally comes right back up, cuts out for less than a second.
2. When listening to XM radio, sometimes a song will cut out for seemingly no reason. No interferrance, perfectly clear sunny day.
3. A few times, I have completely lost all the display from my car altogether, have to turn the car off and restart it for it to come back.
4. A few times when starting the car in the morning or after work or whatever the radio will get stuck on the XM LOADING screen and the radio will never come on. When you try to change to a different input and go to iPod that usually works. In order to get XM to work, again have to turn car off and back on.

Are you guys experiencing any of the above issues and if so, how do I resolve them? Are they all related to the PXAMG or just #1? So frustrated with this thing I am ready to just take it out altogether.
