Initially (before flashing the radio at Harley) the radio worked with poor quality and had a beeping sound coming out of the speakers every few seconds. Everything worked well after the radio was flashed, except I'm not getting the oil pressure reading, instead it just shows ok. I already had the WHIM installed, so car play is not only fast but awesome. Overall, I'm very satisfied with the upgrade, the GTS is noticeably faster than the GT and user friendly. Setting up my iPhone and Sena 20s was a breeze.

Within range is "OK". Out of range is "NOT OK". Sad way to provide engine status if you ask me. Sorta back to the 70's & 80's with "idiot" lights instead of actual gauges.

I wish you were right and I was was wrong as I would like to have an oil pressure readout too.

Maybe HD will eventually offer an upgrade sensor that can be installed to provide an actual oil pressure signal for the BOOM GTS to display on the newer bikes.
