Twolane I hope you are not right, but the HD tech said that it's engineered to work in all modes
Trust me, I hope my impression of the device isn't right too. Reading more of what y'all have written this evening it seems that at least one other user is experiencing the same thing though. That's a three-fer.
Apparently it's doing even less than I'd initially thought it was also. I thought you were at least getting the voice GPS prompts through the new rear inputs whether anything was hooked to the front aux input or not. And that this input was what was overriding whatever inputs were coming in from the front.
The gentleman writing above, however, seemed to suggest that nothing was coming in from the rear. Is that true? Or is at least the audible GPS voice coming through whether anything is occupying the front aux port or not?
