I need information/advice/tips from others that have installed a Blinder M27 x-treme in a 2008 or newer BMW M3 E92 coupe. I installed a Blinder M25 with Cheetah wireless in this same car (still installed) but hit a piece of recap tire that was laying in the road and it apparently damaged one or both of the heads, as the jammer has not worked since. I bought the latest version Blinder M27 x-treme and have heard it is a little more complicated to install. I would like to hear from others with info, advice and tips on how to make the M27 install better and quicker.
On the Blinder M25 that is currently installed on my M3, I mounted the heads in the grille recess immediately on either side of the license plate holder. The unit performed great in this location providing JTG every time, right up to the moment it was damaged. Where I need info/tips/advice most, is on pulling the wire from the heads up through the engine compartment, without taking the front shroud all the way off, if possible. Also, any info why the CPU cannot be located under the hood in the engine compartment would be appreciated. I bought the Cheetah wireless unit with the M27 so I would not have to make any wire runs through the firewall, and if I put the CPU inside the cockpit (as Blinder's instructions say), then I have to make holes or find holes in the firewall to run wire through. I placed the CPU for the M25 in the engine compartment in a weathertight box that came with the unit. I would like to install the M27 the same way.
Many thanks in advance for sharing your knowledge and insight on installation of this unit.
