Like everybody on the list who are enjoying their Vanagon camper, I
like to sleep in a perfect level position. Of course I have level
bubbles on the dash and on the top of the sliding door but I discover
recently a very accurate free applications on the Itunes Store for Ipod Touch call ClinovintageLITE.
This is very cool specially because there is a vanagon side and front view in the main
window . I don't know if it works on an IPhone but I suppose it should.
All you have to do , it is to cut the plastic holder delivered with
your original Ipod Touch packaging if you want to keep your Ipod
connected to the computer or a charger while you are using the
ClinovitageLite application. Even if you don't cut it (because it is optional) ,� the plastic holder
is very useful to get the perfect level and not scratch the back of
your brand new� Ipod like mine. Have Good night...
