Just installed USA Spec iPod adaptor, and the iPod works ok, but now my gps is not working. Taken unit apart 4 times, tried disonnecting battery, had engine running for 40 mins, and still no luck. Disconnected iPod unit and set back to original - no luck. Message on screen saying it is looking for 'satellites'. Everything else on the info screen works. Any help would be greatly appreciated by one very very frustrated owner.
