Thanks for the shots of the STB table. I have just received the chip for my Avant RF and it's labelled Western Europe V4.28. When fitted, I'll post any variations.
Question: where is this chip (IC5 I think) located in the Avant RF? I have already replaced the overall s/w to V10.3 and the AC3 s/w to allow DTS so I thought it would be easy... Looks like diagonally up 1 inch to the left of the main s/w chip (IC6) could be favourite?
Please help, I'd hate to get this far and then mess it up...
