Check that the spring clip takes proper contact to the gold plated contact area on the PWB. Also check that
the spring clip fits well in the Bluetooth antenna and has a proper contact to the wire in the PWB. In case of

Check the solderings of the (ceramic) GPS antenna and the tuning elements. Also check the ceramic
component for cracks and breaks. In case of damage, the PWB has to be replaced.
