Just received this UP-A1, linked to my Onkyo TX-SR608 via the port, turned on my 4g IPod touch and........... it all worked fine, no problems. Did a bit of research 1st as I was worried that (a) it wouldn't dock my 4g touch or (b)the display on my TV wouldn't work, but hey presto no problems. So to clarify the UP-A1 is okay for the 4g Ipod touch and there is no problems displaying contents on screen providing your Onkyo amp is compatible. Everything can be controlled by the SR608 remote. The on screen menu may be a bit simple but thats a minor issue for me. Just make sure your Onkyo amp is compatible.
