Park Heating and heated steering wheel retrofit

[A1GSS]

Hi All

Newbie here and looking for a used X5 E70....

Anyone know whether it's feasible / simple to add or enable the Park Heating (Auxiliary Heater with Remote) feature to a diesel X5 that does not have this feature from new? It's Option #536 from new.

Also the Heated steering wheel...?

Any recommendations for independent experts that could carry this work out?

I can't find a used E70 that has these features so I'm thinking of buying one without, and adding them in...



Thanks.
