Repairing the NavAll could become a challenge. I read Jeff stopped supporting/repairing the units and you would need a very experienced person to replace the screen.
If you have a RunGrace unit (don't know which one) you would probably need an adapter to make it fit.
My advice would be: go with the RunGrace. If it fails after a year or so you can rip it out and replace it with a different standard 2Din unit.
That being said... you might want to look for a replacement for the NavAll with the same look and feel:

The USP for the NavAll (being very well supported) seems to have faded lately...
