a friend of me have a archos 604 and dvr station.
I have a archos 405. we tested the g4 dvr station on my 405 and it works great!!!
. the click cradle fits perfectly.
It can record and display to tv. I don't know how epg works so we didn't tried it. I didn't noticed any bugs but i didn't tried the remote. also the display is in the left corner a little bit curved. (I think it's my tv). I mean you can buy the g5 dvr station with wifi and qwerty remote or you can save (i live in europe) Ôé¼30 (about 50 dollar) and don't use wifi. I don't know how the g5 station works but i thought if you have a 405 you can't use wifi.(i realy don't know how it works)
sorry for my bad english
