I am going to replace my navigation/ stereo touchscreen head unit. I am looking for the replacement and have a question.
The last letter of the part is the revision level.
Is it ok to mix the rev levels or do I have to find the exact match. If I can have any level it (obviously) gives a lot more choices and availability of the unit.
I have been searching but unable to find the answer.
