Installing an Aftermarket Navigation or Headunit
i was putting it together.
just go it installed last week.
right now i just have it tight fitted
and pushed the way back. and i glued
the trim ring so its kinda solid.
but i might have to look for better way.
Thanks!
1.) tool to remove old head unit
2.) antenna adapter
3.) steering wheel control adapter
4.) wiring harness
5.) dash kit, double-din
There are still some issues before I start my install though that I would appreciate help with and hope it can help others. The GPS install manual says to connect one wire to the Speed control and one to the parking brake. Is this necessary? will everything work without doing this? Also, will the speakers work without an adapter for the sound system ?

Regarding the speakers, if you use an aftermarket HU to feed the Bose amp, the speakers will work but they won't sound as good as they would with a converter. If you use either the HU or a conventional amp to power Bose speakers, both the amp (or HU) and the speakers will most likely die over time. 1-ohm of impedance in a system designed for 4-ohms is the problem.
Here are some notes I took when I changed mine.
I hope that helps.

BTW, GiZzos wallpaper looks nice!
As for the steering wheel controls, you will need two adapters. one that is unit specific..swi-jack or swi-ps and you need one that is specific to your connector swi-can-2 for me.
One other piece of information is that you will need to tap into the cigarette lighter to connect the red wire on the harness.
I installed the pioneer x910bt and used the dash kit adt-va133 which looks like it came out of the benz factory.
I will post pics soon
The PAC-OEM2 does two things:
- If needed, it converterts line-level signals to low-level
- It converts the unbalanced differential signal to a balanced, differential signal.
You can always sell your OEM2. Unfortunately, $40 is a little high - I paid $15 from Crutchfield with free shipping.

Do you use this PAC unit instead of the Metra 1748 harness? I had a local installer use a harness without the PAC OEM2 unit and I don't even see where he connected the sub-woofer.
