Cobra GPSM-4000 vrs. Garmin 2610

I have them both, ran a 200 mile test with them both running side by side in my vehicle.
-Easiest to put an address in: Cobra no question
- Best in vehicle mounting: Garmin no question
- least intrusive when a detour required: Cobra
- widest area coverage: tie, both have the entire us
- Fastest on cold startup: Cobra starts faster
- Maps most up to date: Garmin, (I live in the boondocks)
- most intuitive for user: Cobra no question

I like both units, the Garmin however has a longer learning curve.

If I can find a reason, I will buy the new Garmin 7200, it seems to have a lot of what I want, and will let me put the audio thru my car radio system.
