Hi All. First post here after reading this monster thread through over the course of the last few days.. phew.. Great source of information.

I, like a lot of the others here am looking to replace my headunit with something a little more up to date.

My situation regarding the stereo is slightly different to anyone else who has posted in this thread as far as i can see.

Originally my E53 came with the following according to a vin decoder.
S555A - On-board computer V with remote control
S650A - CD Player
S661A - Radio BMW Business (C43)
S672A - CD Changer for 6 CDs
S677A - HiFi System Professional DPS

No mention of NAV system..

My car does however have the widescreen NAV unit fitted with the DVD GPS unit in the trunk/boot. When i remove the headunit/NAV Screen there is clear evidence of plastic being cut away to allow for the headunit/NAV screen to fit. This must have been done by a previous owner at some point!!

In your opinion, do i need to reprogram the DPS to not look for the NAV Screen??

Regards,
Aleks
