Stafford_Mart Posted February 4, 2018 Share Posted February 4, 2018 Hi, I'm looking at swapping my Bose head unit after reading a couple of very good guides on here. My question relates to the voice guidance from the Sat nav, which I've read somewhere, no longer works. Is this the case and is there a workaround for it ie. Modifying the wiring? Also with the replacement unit having Bluetooth I would remove the hands free module fitted. Can I still use the roof mic with the new unit....possibly by rewiring as necessary. Many thanks. Mart.

Adam_Williams Posted July 6, 2022 Share Posted July 6, 2022 Hi Mart, Not sure if you're still around on here or worked out if this can be done but I find myself in the same predicament. I have a 2008 HR with Bose and Nav. Want to swap out the Bose HU for a double-din but do not want to lose the audio from the stock Nav. Did you find a solution? All the best, Adam Quote Link to comment Share on other sites More sharing options...
