I have a 2012 ZVW30R with a JBL Greenedge 57038 6" Touch screen unit. I want to add a Sat Nav unit, but it needs to integrate with the Greenedge which uses special low power speakers. Otherwise I'll need a compete new head unit. I've found an add-on GPS for the ridiculous price of $(Australian)1450. And I've found Chinese head units for $450-$850 (Vigo and Xudox). Has anyone got any suggestions (other than buying a Garmin/Tom Tom portable?).
Thanks, Harold. I wasn't even aware such interesting devices existed. However I have this expensive-looking JBL Greenedge touch screen head unit, and it seems a shame not to be able to use it for GPS.
