I use my GO 730 as my Bluetooth device in my car and I was able to download QuickGPSFix updates from the device through the cell phone. Now I cannot do that. The device tells me it cannot connect and to check my cell phone. I don't know what to check. I use my phone to "tether" my laptop for internet access and that still works perfectly. Also the Bluetooth works perfectly. Is there a setting that I'm missing?
