Well, I got it installed today. So far I'm liking it. It does seem slow on boot up even with the 2.0v. But I noticed my factory sub is not coming on. I replaced all factory speakers with Boston Acustics so I didn't notice it wasn't on until I put my ear up to it. Any suggestions on how to get it to work? There were no separate wired that I saw in the harness for it...

I also have to edit a bunch of numbers in my cell so the the contacts on the radio are easier to use...

I don't know how your sub is connect or if you're running an amp. Can't help you there.

In addition to editing your phone as is described in other posts, you could also boot into testmode (see other threads on how to do that), copy the phonebook database, download a program somebody posted on here that will let you edit your phonebook and even reorder entries, and then put the updated file back onto your head unit. You'd have to search for the threads that explain how to do it. This worked great for me and I am endebted to all those who made this possible.

Thanx for info & responding, the sub is factory amp powered. All wires to PAC harness are good and triple checked. The only wire not hooked up is power antenna. PAC and Pioneer have blue/white amp wires that are connected together.

There is a setting to turn a sub on or off but I don't know if that's the solution to your problem. I've never had an amp or sub. Maybe somebody else can give you a better idea.

Tried the sub settings, no go. I don't notice because this unit sounds much better than the factory HU. I can imagine how it will sound if i can figure out why it's not working.
