Pay More Attention On iPhone 6 Map Navigation Diagnostic

iPhone 6 map navigation is not a common fault, which means we also need to check it carefully.

Honestly, not all of our phone faults are familiar with us, we still need to pay enough attention on it.

While according to the attached file, we know the iPhone can be positioned, but the location coordinates don't move when the navigation route, this failure may be caused by signal instability, or the GPS signal channel problems.

First test the iPhone 6, open the Maps App, the location coordinates is not updated when navigating, and it always in the same place.

Disassemble the iPhone by phone opening tools, remove the iPhone motherboard. Open the WUXINJI Dongle to check iPhone schematic diagram, the GPS signal through some switches to the U_WTR_RF RF IC and then to the iPhone baseband CPU, as shown in

Some small switches are covered by black glue, so we're not consider this factor first. Because it was first passed through the U_WTR_RF RF IC and then to the iPhone baseband CPU，so we can replace a new U_WTR_RF RF IC.

After replacement, install the iPhone to test, the navigation route update location can move normally, the repairs end!

This failure is caused by the damaged U_WTR_RF RF IC.

Then it means we got the result we want, next we will use the professional tools to disassemble it and repair it.
