Hello, I didn't find any info searching the forums to this question, so I figured I should post. I currently have an AVIC-Z2 w/ a PAC steering wheel control and Blue tooth. The unit is connected to a 4-channel amp (RCA) and a sub amp (RCA). I'm looking to replace the unit with an AVIC Z110BT (upgrading later to a Z120BT via software). My question has to do with the physical installation. Do the connectors/harness match between the units? Are the microphone and GPS antenna interchangeable? Thanks!

I got an expanded drive a while back w/ a Z3 upgrade and just recently had my maps updated. Very quick turn time on Garret's part for both (same day in my case). Just a little on my background; it's IT related and I've worked with a variety of file systems over the years (including TiVo and some other consumer units). I could do this myself, but Garret has done this many times before and it's always done right. That's just my take. Thanks Garret! Frank

I'll put in a second plug for Garrett's drives. I bought one and it works well.
