30 Jan 11 How to connect a bluetooth GPS to a Ipod touch / Iphone / Ipad?

Roqy – Bluetooth GPS uses SPP (serial port profile), but Ipod Touch /  Iphone / Ipad only support HFP (Hands-Free Profile). Natively, Apple does not provide SPP to connect an external bluetooth GPS.

You may have to “Jailbreak” the Ipod Touch / Iphone / Ipad and use the application “Roqy” to connect external bluetooth GPS antenna to your iPad/iPhone. For detail, please refer to http://www.roqy-bluetooth.net/wp/
