HTC Touch (CDMA) / XV6900

I don't have your answer sorry to say, but just wanted to make sure you are going to Howard Forums for help too. Together between Phone Scoop and Howard Forums you can find 90+% of what you need. I am guessing you have successfully linked your GPS by bluetooth to start with. You probably have to go into your navigation (wherever that may be) and look at advanced options and make sure to make a selection to get information from the BT GPS receiver. But never fret someone will post an answer to your question with expert advice soon. If you can't wait try Howard Forums. I wish you well.

From what I know, GPS recievers can only operate the "phone" feature with bluetooth to make and recieve calls. I haven't heard it ever being able to send and recieve GPS data to and from the phone.

What exactly do you want the phone to do?
