Curt, It may seem like the power connections are the same but they are not. The power connector on the back is strickly a power connector. The mini-b connector on the side can be switched internally for supplying power or for charging. Garmin uses the ID pin to "sense" what is connected to the side port. Each of Garmins chargers has a different value on the ID pin. The AC charger has 15k ohms between ground and the ID pin and 15K between power and the ID pin. The FMI cable has 8.2K between the ID pin and ground. In this case, the unit knows it must supply power to the cable and does an internal configuration where it makes sure power is connected on the back. Hence the message a device requires power.
You should be able to find a replacement cradle. Garmin still refurbishes the 350's and would have parts available. They have shown up on eBay also.
