Shoved about 20 bucks worth of parts into the AM Radio for this: I can give more details if anyone wants, its hacky but seems to work well, just need to see if it lasts.
Yeah, I'd like to hear about your work. I don't think I have anything that uses bluetooth, yet, but I might some day.
So I don't have pics of the construction, but it all centers around this: http://www.amazon.com/Nobsound®-Blu...&redirect=true&ref_=oh_aui_detailpage_o06_s00 Basically I removed enough of the stock guts to make room, connected the back of the stock volume knob to where the BT units knob formally was and that was it. I did have to cut the metal on the case to make room. If I did this for a customer I would probably replace the case sections with ABS. Also a lot of hot clue was involved, we will see how that lasts...... The unit is hooked up to a couple of Pioneer 6x9 speakers I had from another project, sound is very good but a balance control would be nice as well as an EQ, but I'm being picky as this is 1000 times better than what the car came with and was inexpensive.
I want to do something similar while still keeping it AM... If not, I may get a NOS AM radio (as mine doesn't have one) and install it, then add stereo speakers in the cargo area underneath the bed and add an aftermarket stereo in the glovebox!
