7530 Vs7530t

[johnj]

We have been useing a7530 for several years infact we had a proto type in one of our cars.
What is the diff. between the two and should we up grade at least the one that is in the C/ED
car.
Do you have an ugrade or trade policy?

johnj,

First and foremost let me apologize for the delay in responding. There unfortunately is not a trade in policy on these units.

Thanks,
