We are in the process of acquiring one type of V12 fix. It is a combination of the Diode fix and the Matrix PIC fix. This will be offered in addition to an install in the V12's for a small fee of $10 for those that feel they would like something like this. It looks like this.
Weather its needed or not I cant say 100% but some people fell some sort of fix is needed. We have installed a few v12's now with no fix and they are still working fine.
