NavFone - navigation on the iPhone/ iPad

I have installed the NavFone (from AGIS) on my iPad. I bought it for $2.99. It is excellent, and works better than the GPS navigation that I installed in my car (which cost nearly $300). It is easy to use and have map for Singapore and Malaysia. My challenge is to install a holder for my iPad in my car, so it can provide navigation guidance while I am driving.
