I recently had a Bel RX45 installed with the M4 jammers in my 2005 Toyota Avalon. From reading here I think this may not be ideal for my vehicle.
(edit: I found the answer to #1 in the FAQ)
1) Can I install a Blinder M27 system and run it at the same time as the M4? Or should I yank the M4's and use the Blinders exclusively?
2) Would you recommend the Blinder M27 or something different?
