I found a iQue M5 in my office with a dead battery. I ordered one, but also had a prompt that the backup batt. was extremley low & 48 hrs. of charging would rectify the prob. The unit worked great in the cradles, but immediatley died upon disconnect. Curosity killed the cat and I proceed to perform surgery seeking the backup battery to order as well. Needless to say, when I reassembled the unit, it was DOA! Can you repair (price?) or offer a quick fix? I have tried the eset button. Thank you.

Hello there, i can fix the device by re-assembling the components for you. Offering a quick fix will be useless as the device might have been improperly re assembled. Accept the solution and contact me.

Hi. If the unit stop working after dis-assembly, you may have to send your unit to a service center.

Hi, well these are extremely delicate instruments, indeed. When the battery goes Flat, it can and does cause a plethora of problems compounded by the fact that the "Internal" battery was also somewhat "dead'. When this type of thing happens it can screw up the contents of the internal memory. This in turn causes the device to refuse to power up properly.
But, IF you have replaced successfully BOTH batteries, and you are sure they are OK, Then maybe it will be possible to update or the like via, the internet, if you can hook up to a PC, and run the Garmin software and see if it will update and this may remedy your situation.
However the most cost effective and practical way to effect a repair with a device such as this is to simply return the unit to a local Garmin center, and they will perform a quick, inexpensive repair, with a warranty too.
