Aux and Bluetooth Retrofit for 7th Gen Civic
A month ago I bought a 2005 Honda Civic to get around the bay area and take some road trips. So far it’s taken me many miles with no issue – last week I drove from SF to LA via 101 on a single tank of gas (36 mpg).
A good soundtrack and/or audiobook is vital to the roadtrip experience and I decided that the built in CD player and FM receiver just wouldn’t cut it. I went the aftermarket head unit route with my last car and although it worked ok, I was disappointed with the gaudy appearance and poor UX. Aftermarket stereos are also known for attracting window smashers. Several years later and I still don’t know of an aftermarket car stereo that’s much better than the one I had.
Here’s how I retrofitted an auxiliary input and bluetooth module without replacing the stock head unit.
- Install the aux adapter
- Remove the leftmost plastic Honda panel piece to fit the bluetooth module
- Drill two holes in one of the panel pieces to fit the jack and switch
- Solder the panel mount jack to the other end of an RCA cable
- I had to remove the plastic casing from the switch to get it to fit
- Solder some leads to the rear of the cigarette lighter to provide power to the bluetooth module
- The 12V adapter doubles as a USB charger so I ran an extension cable under the steering column to my iPhone mount
