I have a Honda Insight with and inbuilt GPS/SATNAV system. I want to disable this so that it no longer automatically/continuously scans + picks up the satellite signals. Can this be done? if so how easy/difficult is it. At the moment I have been quoted that it will be 1 hour's labour, which is expensive, and that they cannot guarantee it will stop picking up the satellite signals. Ideally I want to keep the radio connection but I do not want to have the signal continuously updating - even when I don't need to use the SatNav.
