While changing the battery on my Garmin Nuvi 680, the most internal cable disconnected from its connector and I don’t know if the connector lifts vertically, slides out or is soldered to the motherboard. Beyond that, I don’t know how to reattach the cable. thanks
Scott Hoffman, you did say the innermost cable. Take a look at the attached image. Flip those clips in an upward direction with your fingernails gently toward the direction away from the cables. Hope this helps, good luck.
