Why GPS software always miss voice guide when phone call coming

[jerrywei]

Hi1
My D810 always miss the GPS voice guide when there is a phone call coming.I must exit the GPS software and enter again,then the voice guide work again.The same problem for all GPS software.It's not safety for me when driving and using the D810 together.

Trinity's processing power (or signal interference) prevented both voice and GPS operate at the same time. Therefore, if there's any ongoing phone call, the GPS will be automatically stopped. This was the design by HTC.

I believe to re-enable the GPS operations after phone call, the GPS port must be re-opened. Apparently, your GPS navigation software was tricked by such abrupt interruption of signal and didn't retry re-opening the GPS port, and hence you end up with a "dead" voice that requires a restart.

I think it is a usability bug of the GPS nav software which don't take into a/c of random signal interruption from the GPS chip. The root fix is to ask the vendor to have a timeout feature implemented.

That said, some GPS intermediary software such as GPSGate seems to retry opening the GPS port regularly if it times out for a certain amount of time. So it can be used to alleviate the problem you have.

Then how about if you are not using gpsgate?

Ok, now back to gpsgate, do you check in the Input option page:
1. Retry connection on error
2. Close input on power off?

I guess those 2 options may help.
