OK - an installer hooked up the Avic f7010b4 Nav system. It's in effect the same as the f700bt. I have a few questions comments:
1. The system really rocks. I was worried reading some of the things here. I find the ipod integration very nice. Had only one random reboot when messing with a lot of buttons at once.
2. In 2d map mode, can you change the orientation to whatever you are facing? It seems it always gives you North orientation.
3. My FM reception is much poorer than the OEM radio. I am in a Chevy Express Conversion van. I just scanned the technical manuals and it doesnt seem to have a powered antenna in there. Is there a way to boost the antenna in the radio? Buy something inline?
4. The sound quality is not as good as the OEM radio. I have adjusted some things, but I guess the next step is to get better speakers/amp, etc. It just seems like too much bass is coming across, distorting the sound. I lowered the lows to the lowest setting. Guess I will play with it some more.
5. Overall - it's SO easy to use. Backup camera rocks! Just love the system. I come from owning Lexus/Toyota vehicles and this nav is about as fast and much more intuitive. Love it!
