One question

If I buy a second hand module CA can I swap myself or do I have to take it to fraud?

Whats a CA....

so

I thought all T's have bluetooth

Three are three bluetooth modules.

AA

BA

CA

Called bayford coburg and was told the process takes 2 hours and the charge is $120 if I have the module gee

Whats the difference between the modules?

I heard the latest module works well with the iphone 5. also adds the name as well.

I have alot of dropouts and cant answer on the first module!

I have that issue with mine, ill have to check module for code.

Can they not update the module software.

no they cant the bastards no wonder there broke!

The iphone bluetooth stability issues are to.do with the phones design itself. The problem is the wifi antena is right next to the bluetooth antena and it causes interference if wifi is switched on. Switching the wifi off will help with bluetooth stability but will not entirely prevent iphones dropping out. All manufacturers have this issue as apple is not very friendly with sharing software etc. The bpm (bluetooth phone module) is vin coded to the acm (audio control module), fdim (front display interface module) and aim (audio interface module), therefor all 4 modules MUST contain the same vin number for the systems to work, hence the need to program the new module
