Portable Navigation: Anyone Own One?

Duner, the Garmin has an external speaker thats built into the power cord that plugs into the lighter. I had the original Garmin Street Pilot in my S2000 and I had a stereo installer pull apart the speaker and relocate in in the A pillar. Its funny how somones opinon changes on something AFTER they have tried it. I give you alot of credit you know how good navigation is and SAY SO even though that means agreeing with me. It certainly appears that some things also never change like people thinking navigation is totally worthless without ever owning it. There are alot of things I can do with $1100.00 on my car. That would cover a CAI and tune. I already have 300 HP and the lousy 25 or 30 HP I would get from that can't compare to the convenience of navigation. I also learned the hard way that no matter how much power I have I always want more so this time round I will focus on enjoyable toys like navigation, stereo equipment etc.
