Unfortunately, I bought a 49tx just prior to the 49txi coming out. As the 49txi was rolled out Pioneer said they were going to offer a TXi board upgrade for $500.00 for the 49tx but to my knowledge, they never made good on the promise. I have a AV-59AVI and want to buy Pro-1120HD very soon. I have space constraints and really want to get the benefit of i-link. Are there any boards available I can obtain to convert my 49tx or any other options besides a new receiver? Thanks!
