It seems I've gotten myself into quite a mess. I have an 03' Accord coupe with the stock navigation in it. A few months ago, the navigation blew out and I decided to replace it with the D3. Since there is no dash kit for the dual climate control double din, a custom audio shop near me said they would fabricate one. After taking out the stock unit, they found that all the A/C controls were tied in to the unit. If they were to install the Avic-D3, i would lose all heat and air control. Has anyone tried this install, and if so, how did you do it? Any ideas?
