Thanks for the insights, here is what Adam at Powerlet in Michigan pro--offered as a solution:
Bill,
Thanks for the kind words. The Ipod is indeed a product that we have on our books. Ipod has a built in regulator for on the A/C power cable. We can garner the connectors no problem but without stepping the power down through a regulator, we would end up burning the units up. We are finalizing an adjustable regulator but it will not be to market for some time.
As for your situation, If you tend to ride like mostGS riders with a tankbag, might I recommend our PTB line of products. They are easy to install through the side walls of soft and hard sided luggage. Once installed, the ability to power the Ipod and Gerbings apparel and whatever else in the future, is right in front of you.
For starters, check out this link:
PAC-007 on this page to split the power off your one outlet:

This way you can keep the GPS on the ram mount and have the power available just like you had it.
The tank bag products I'd recommend are here:
PTB-006 for the tankbag setup.

This will enable you to install the bulkhead into your bag and connect to the available outlet port you still have up front.
On the same page check out the PAC-026 or PAC-027. This will branch off inside the bag and provide enough connections for the Ipod and your Gerbings and again anything you wish in the future.
As for the final cable for your Gerbings, if you have the older style with the SAE, you can now connect right in the bag on the spare SAE port on the PAC-026. If you have the newer coax connector, you will need the PAC-027 and use Gerbings adapter cable with the BMW male or buy one from us.

Hope this helps and I hope I have not confused you too much. We all ride with powered bags here and its very convenient. Especially when you need to park and get off your bike. One easy disconnection of the tankbag and you are good to go.
Let me know if you need any further help.
Ride Safe,
