OK. That's what I thought. Thanks for all the help. You guys made my decision easy!

Thanks for the great info! I think I'd prefer to use the 1725 and keep the installation a little more simple. My guess is that the sound quality will be good enough for me and my typical non-audiophile listening habits. Would you guys suggest going with the 90BT's 4V preouts? Would the extra voltage cut-out the potential noise better?

One other option for you... You could look for an FM amplifier to insert between the GM-Universal plug conversion and a Y adapter. That would get you much of the antenna performance back that you lose from splitting/converting and would avoid installing a second antenna.

I should say right off the bat that I don't own the 910HD, so take what I say with a certain grain of salt... Having said that, I can tell you that the common review of the 910 is that it will cut your FM range significantly even if you wire the car's antenna directly to it without splitting it. The reviews are mixed, but my read on it is that unless you are driving inside of a major city, the 910 won't work well for you. I'm not sure if the problem is with the pioneer engineering or with HD radio itself, but the common conclusion I've found is that unless you really want HD radio a

That seems to agree with what you'r

Thanks for the speedy reply! The Bose system has an amp for the main speakers which relays to a second amp for a woofer. According to the service manual, (I've never removed the OEM HU to see for myself) it is hooked to the OEM HU via wires through a traditional harness. My car is an '02 Acura RSX-S. I don't know if this is helpful or not, but the service manual's description of the security system says that the system is armed when the doors are locked, the key is out, and the hood is closed. At that point, the HU is monitored via the security wire. In the security troubleshooting

I'm currently considering buying the 700 or 900 and leaning towards the 900 because I'm worried about the 700 being less accurate since it doesn't have the VSS/G force sensors. I've heard about the 700 telling you you're at your destination when you're still a block away. My first question is this: Is the 900's speed sensor worth spending the extra money on? My second question regards installing the AVIC into an Acura RSX-S with the Bose system. Looking at the 700/900 installation manual, there appears to be two methods of hooking the HU to the speakers -- either through wires or RCA c
