Is anyone else experiencing this, or can verify this?

I bought a k750i recently and used it for a few days in the car before updating its firmware to version R1AA008 from version R1N035 (I think anyway, I didn't have that version installed long). Now I don't know if these problems were with both versions of the firmware or not, so I'm hoping someone can verify if they're having similar issues with either/any version with the k750i:

1. RM always appears below the signal strength in the HUD, as if to imply that I'm roaming, which I'm not.

2. Signal strength is weak! I often have garbled calls.

3. Signal strength indicator on HUD does not update. If I start the car in an area where I have, say, 2 bars, then drive a bit, the bars don'e increase or decrease. I checked my phone in an area I know has great signal, and it showed full bars while the car showed only 2.

To check the firmware version on your phone, do this (< or > indicates joystick movements) from the main menu:
