Wow, I'm kind of glad to hear that it's not just my phone having this problem. I find this so incredibly frustrating.
I have a T-Mobile Dash running Wm5. Pioneer keeps telling me "invalid device". Anyonek now if the Jetware product will help me out?
Thanks,
Chris
ETA: Well, I installed this and it did something. Somehow I got the phone to think it was connected. And the pioneer actually displayed battery and signal strength. And a 'disconnect' button. Butt I couldn't make it dial, or talk to the phone in any useful way.
