Qualcomm

Maybe I misunderstood your situation but if the external keyboard is slowing you down and you don't have an official stylus you can use a ballpoint pen with the ball retracted. Or your finger. The one in my truck works fine.

 

I think there is a bug in the sound system. I used to change the speaker settings to use the internal speaker until I noticed some strange stuff in the event log. It was trying to change it back to external and reboot.

I've noticed when it's set to external speaker there are a few screens that won't steal the audio from one side of the truck. Like performance monitoring will steal the sound but changing to Settings will bring it back. It seems if you keep it somewhere where it isn't stealing the sound it won't get laggy.

It's a pita, Everytime a new message comes in it will steal the sound. Reading the message and going back to Settings seems to fix it...

I remember a company safety meeting where they mentioned Qualcomm knew about the issue and we're working on a fix. That was at least three years ago.

 

To Reboot a Locked Qualcomm MCP200, you can.

1. Go to the Home or Main Screen

2. Press and Hold the Text-to-Speech Button located on the upper top right of the Unit for eight seconds.

3. After the eight seconds have elapsed, release and immediately hold the round middle button located in the Five Way Control Pad (located just below the button you just released) for another eight seconds, the Unit will turn off and Reboot itself.

This will Reboot your Locked or Erratic Cursor on your unit.

 

The OP does not have the system with the integrated physical keyboard (and associated buttons). I prefer that to the little screen with the screen keyboard like what we/I have)

 

Maybe they should have called it a MCP 150.

 

Mine is always slow. It even shuts down sometimes for no apparent reason and reboots. I just ignore it, to be honest, and keep going. When its slow, I wait on it to catch up. It is frustrating, but I really don't worry about it much.

 

The buttons aren't on the keyboard they are on the main portion of the unit.
On mine I only have to hold down the talking head button for about 10seconds then release and it will reboot a frozen screen.

 

No worries.
But, I haven't any clue on that unit hopfully someone that does will be here to help you.
