I really like the R-Magic holder but they don't and won't make a LHD version. I bought a bracket on ebay for my F-150 (cause it was $1) and thought about screwing it in to the dash for the RX-7. But came across this universal one that may be an even better, cleaner and cheaper solution. I've been using velcro but over time it pulls off and doesn't stick. This version slides in.

That sounds better than my commander holder which rattles over bumps.

 

I cut up a 12v cigarette lighter adapter plug and epoxied it to the back of my commander. Did this on my old car and my new car. Here is a picture of the old car...

 

^ that's a perfect location out of the sun so it's easier to read the screen but my Pivot shift light is plugged in the the lighter and others would loose the plug to charge their cell phones.
