I have a Z110BT that has been firmware upgraded to the 120bt software (latest update 2.003). It has been intermittently not responding to any touchscreen presses. Can't even press "OK" on the nav startup. Restarting the car usually (but not always) fixes it.

Does this sound like hardware or software problem?

Should I try to reupdate firmware?

Thanks

Sounds like a screen issue.

Sounds like a screen issue.

Some new info on this. Happening more frequently now. When starting car have no sound and no touchscreen response. Only hard button that wold is mode. After about 10 minutes everything starts to work properly. Hard to believe it is really a hardware issue (screen works perfectly when working at all).

Are any known software issues with the firmware upgrades (was a 110 but upgraded to 120 software with all updates applied (003 rev)

Thanks

Regardless at this point your unit is defective. Have it swapped or exchanged.
