I just had my PDIM replaced last week. At first it was supposed to be Monday, but when I brought it in, the hardware wouldn't accept the new software so they had to order a new PDIM for me. Two days later, they had the new part for me and put it in. It's DA/DX and it works very well, now; although it does need to spend quite a bit of time indexing 20+GB of songs every time I start the car. :p
I know that people say that it doesn't have anything to do with the Bluetooth, but now when I stream audio from my phone, it doesn't cut out and then switch itself to another audio source any more.
Now... If only I could find a way to make the up and down rocker make it jump between stations in my BBC iPlayer. :p
Back in the shop to get the spoiler fixed. :/
