Can someone tell me how to use my Acura TL Bluetooth with my cell phone?........... Please!

 

The owner's manual describes the process @ p.157 for the 2005: https://techinfo.honda.com/rjanisis/...505MAINIXA.pdf.

The 3G TL Service Dept thread has links to a number of features, mods and issues, including to every years' manuals for the 3G TL at https://acurazine.com/forums/3g-tl-2004-2008-93/j-020-3g-acura-tl-owners-manual-navi-manual-warranty-booklet-pdfs-851625/.
