I recently installed the GROM BT-3 (XM firmware) in my 04 TL. I'm currently going back and forth with GROM tech support and am on my like 3rd or so firmware. It has gotten better, but it is still cutting out and there are times when I have to use pause/play on my phone to get it to reconnect.
I have a question about whether I installed it correctly. When I plugged in the GROM into the back of the radio, I DID NOT plug in the original plug that was in the radio back into the GROM supplied Y harness. My rationale was that I was disabling XM by no plugging it in. However, in searching the forum, I have seen others talk about disabling it by unplugging the XM module in the trunk. Does it matter which of these connectors are unplugged, or is it the same??
