iPod touch iPod Touch 5 Generation and external GPS Bluetooth

[vincenzo79]

Hello all,
I have a iPod Touch 5 Generation and up to version 7 of IOS, the internal GPS has never given me any kind of problem.
Unfortunately, following the update to IOS 9, I started to have many problems with the GPS, in particular, I started having problems with applications such as RunKeeper or Runtastic.
I would like to use an external GPS antenna via Bluetooth and I wanted to understand if there were problems, but above all I wanted to know if the ipod in this case, IOS 9, accept the communication via Bluetooth.
Do you think there are problems ?
Thanks,
Vincenzo

There is no internal GPS in either the 5th or 6th Gen. iPod Touch.

I guess he means the WiFi based location systems.

Thanks to all for the response.
But what I don't understand is that before the update to version IOS 9 for iPod, the application Runtastic gave me a lot of time in line with the race.
After the update, instead, the times have changed completely, while using an iPhone 4S, which from what I understand, it should have the internal GPS, the times are the ones that I did with the iPod before the update to IOS 9.
I don't understand how it can never be a success.
A problem with the Runtastic app ?
