Nokia 2710 Navigation Bluetooth Problem Solution
Heres the solution that might help to fix Nokia 2710 Navigation Edition bluetooth problem.
If the nokia 2710 failed and cant establish bluetooth connection to the other device this sometimes caused by a flash firmware problem. Updating or restoring the device flash firmware will might possibly fix the problem.
In some cases bluetooth failure is caused by a faulty hardware components, and this can be shown by this solution below.
This Solution may also works for Nokia 2710 FM radio and GPS problem.
In Nokia 2710 the bluetooth chip is mounted located near the interface connector and it is being covered by a shielding metal. You may first check the chips supply voltages indicated on the solution above.
the the highlighted capacitors is were the RF clock signal that feeds to the bluetooth chip. For advance troubleshooter they start to check the frequency data on that spots before trying to rework or replace the bluetooth module chip.
If the supply voltages and the RF clock capacitors were both okay, you may then proceed to rework and replace the bluetooth module chip. A faulty bluetooth chip will also result to FM radio and GPS failure.

Nokia 2710 Navigation Edition No Network Signal Solution
Heres the solution for Nokia 2710ne that have No network signal problem. This problem happens when the device suffered wet damaged or accidentally dropped.
For a water damaged Nokia 2710, you must ensure to clean the PCB board first before proceeding any software and hardware repair. And for accidentally dropped units like it shows a dropping signal indicator on the display, you may restore and or update the flash firmware first before you attempting hardware repair.
If the phone does not being fix through firmware restoration, you may then proceed to do a hardware check up and troubleshooting.
The solution below shows which particular components that may need to check, trace and or then replace if found damaged.
Hints for repair:
Before you may proceed you must see to it that the antenna terminal contact expander were not damaged nor misaligned and it has a proper connection to the antenna module. A poor antenna connection also results to poor, dropping, and or no network signal receptions.
If the antenna connection is okay, you may then proceed to work on the RF Power Amplifier.
Check the RF PA chips supply voltage, this voltage is feed from the phones battery 3.7 volts.
If there is no voltage reading, trace its line paths through to the battery connector positive terminal. Just manage to apply jumper wire on it if the line is cut, fot it is the only option.
If the supply voltage is okay you may then remove the RF amplifier chip. Check all the solder bumps if there is already lifted or damaged. Install a new RF power amplifier. In most cases a damage RF Power Amplifier result to No Network Signal like on nokia 2710 navigation edition.
