705 with multiple ANT+ devices?

[protege55]

Has anyone had experience using a singular Garmin 705 with more than one ANT+ device (i.e. a Quarq and a powertap wheel). The question comes as a result of having 2 bikes - one with a Quarq system on it and one without. A used powertap on some other wheels would make me "powered" on the non-SRM bike, but I don't want to run data from both a powertap head as well as the 705...thoughts?

Tried to search prior to posting, but found nothing

Thanks in advance.
